================= Etc ===============
[M-x replace-string] : unconditional replace
[M-%] : find and replace [space/y (yes) | DEL/n (no)]]

emacs -l .emacs-ede.el tree.c

=================  Hightlight ===============
C-x w r : unhighlight-regexp
C-x w h : highlight-regexp

=================  Diff Mode (M-x diff) ===============
M-n
Move to the next hunk-start (diff-hunk-next).
This command has a side effect: it refines the hunk you move to, highlighting its changes with better granularity. To disable this feature, type M-x diff-auto-refine-mode to toggle off the minor mode Diff Auto-Refine mode. To disable Diff Auto Refine mode by default, add this to your init file (see Hooks):

          (add-hook 'diff-mode-hook
                    (lambda () (diff-auto-refine-mode -1)))

M-p
Move to the previous hunk-start (diff-hunk-prev). Like M-n, this has the side-effect of refining the hunk you move to, unless you disable Diff Auto-Refine mode.

M-}
Move to the next file-start, in a multi-file patch (diff-file-next).

M-{
Move to the previous file-start, in a multi-file patch (diff-file-prev).

M-k
Kill the hunk at point (diff-hunk-kill).

M-K
In a multi-file patch, kill the current file part. (diff-file-kill).

C-c C-a
Apply this hunk to its target file (diff-apply-hunk). With a prefix argument of C-u, revert this hunk.

C-c C-b
Highlight the changes of the hunk at point with a finer granularity (diff-refine-hunk). This allows you to see exactly which parts of each changed line were actually changed.

C-c C-c
Go to the source file and line corresponding to this hunk (diff-goto-source).

C-c C-e
Start an Ediff session with the patch (diff-ediff-patch). See Ediff.

C-c C-n
Restrict the view to the current hunk (diff-restrict-view). See Narrowing. With a prefix argument of C-u, restrict the view to the current file of a multiple-file patch. To widen again, use C-x n w (widen).

C-c C-r
Reverse the direction of comparison for the entire buffer (diff-reverse-direction).

C-c C-s
Split the hunk at point (diff-split-hunk). This is for manually editing patches, and only works with the unified diff format produced by the -u or --unified options to the diff program. If you need to split a hunk in the context diff format produced by the -c or --context options to diff, first convert the buffer to the unified diff format with C-c C-u.

C-c C-d
Convert the entire buffer to the context diff format (diff-unified->context). With a prefix argument, convert only the text within the region.

C-c C-u
Convert the entire buffer to unified diff format (diff-context->unified). With a prefix argument, convert unified format to context format. When the mark is active, convert only the text within the region.

C-c C-w
Refine the current hunk so that it disregards changes in whitespace (diff-refine-hunk).

C-x 4 A
Generate a ChangeLog entry, like C-x 4 a does (see Change Log), for each one of the hunks (diff-add-change-log-entries-other-window). This creates a skeleton of the log of changes that you can later fill with the actual descriptions of the changes. C-x 4 a itself in Diff mode operates on behalf of the current hunk's file, but gets the function name from the patch itself. This is useful for making log entries for functions that are deleted by the patch.

==================== gud gdb ======================
gdb-many-windows : t (M-x gdb-many-windows)

C-x <SPC>    Set a breakpoint on the source line that point is on.
C-c C-l
C-x C-a C-l
    Display in another window the last line referred to in the GUD buffer (that is, the line indicated in the last location message). This runs the command gud-refresh.
C-c C-s
C-x C-a C-s
    Execute a single line of code (gud-step). If the line contains a function call, execution stops after entering the called function.
C-c C-n
C-x C-a C-n
    Execute a single line of code, stepping across entire function calls at full speed (gud-next).
C-c C-i
C-x C-a C-i
    Execute a single machine instruction (gud-stepi).
C-c C-p
C-x C-a C-p
    Evaluate the expression at point (gud-print). If Emacs does not print the exact expression that you want, mark it as a region first.
C-c C-r
C-x C-a C-r
    Continue execution without specifying any stopping point. The program will run until it hits a breakpoint, terminates, or gets a signal that the debugger is checking for (gud-cont).
C-c C-d
C-x C-a C-d
    Delete the breakpoint(s) on the current source line, if any (gud-remove). If you use this command in the GUD interaction buffer, it applies to the line where the program last stopped.
C-c C-t
C-x C-a C-t
    Set a temporary breakpoint on the current source line, if any (gud-tbreak). If you use this command in the GUD interaction buffer, it applies to the line where the program last stopped.
C-c <
C-x C-a <
    Select the next enclosing stack frame (gud-up). This is equivalent to the GDB command ‘up’.
C-c >
C-x C-a >
    Select the next inner stack frame (gud-down). This is equivalent to the GDB command ‘down’.
C-c C-u
C-x C-a C-u
    Continue execution to the current line (gud-until). The program will run until it hits a breakpoint, terminates, gets a signal that the debugger is checking for, or reaches the line on which the cursor currently sits.
C-c C-f
C-x C-a C-f
    Run the program until the selected stack frame returns or stops for some other reason (gud-finish).

If you are using GDB, these additional key bindings are available:

C-x C-a C-j
    Only useful in a source buffer, gud-jump transfers the program's execution point to the current line. In other words, the next line that the program executes will be the one where you gave the command. If the new execution line is in a different function from the previously one, GDB prompts for confirmation since the results may be bizarre. See the GDB manual entry regarding jump for details.
<TAB>
    With GDB, complete a symbol name (gud-gdb-complete-command). This key is available only in the GUD interaction buffer.



==================== Version control ======================
C-x v v     vc-next-action
    perform the next logical control operation on file
(C-x C-q     by default, C-x C-q is no longer bound, so it's better to use the above binding)

C-u C-x v v
    To switch between branches, type and specify the revision ID you want to select

C-x v i     vc-register
    add a new file to version control
 
C-x v I        vc-log-incoming
    Display the changes that will be received with a pull operation.

C-x v O     vc-log-outgoing
    Display the changes that will be sent by the next push operation.

C-x v ~     vc-version-other-window
    Prompt for a revision of the current file, and visit it in a buffer of its own

C-x v =     vc-diff
    Compare the files in the current fileset with the working revision(s) you started from. With a prefix argument, prompt for two revisions of the current fileset and compare them. You can call this command from a Dired buffer (Dired)

C-x v D     vc-root-diff
    Compare the entire tree corresponding to the current fileset with the tree you started from. With a prefix argument, prompt for two revisions and compare their trees.

C-x v g     vc-annotate
    Display an annotated version of the file: for each line, show the latest revision in which it was modified (vc-annotate).    
   
C-x v d     vc-directory
    View VC-Directory-Mode.
   
C-x v s     vc-create-snapshot
    tag all the files with a symbolic name
   
C-x v r     vc-retrieve-snapshot
    undo checkouts and return to a snapshot with a symbolic name

C-x v l     vc-print-log
    show log for current file (not in ChangeLog format)
   
C-x v L     vc-print-root-log
    Display the change history for the current repository
   
C-x v a     vc-update-change-log
    Visit the current directory's change log file and, for registered files in that directory, create new entries for versions checked in since the most recent entry in the change log file. ().
    This command works with RCS or CVS only, not with any of the other back ends.

C-u C-x v a
    As above, but only find entries for the current buffer's file.

M-1 C-x v a
    As above, but find entries for all the currently visited files that are maintained with version control. This works only with RCS, and it puts all entries in the log for the default directory, which may not be appropriate.

C-x v m     vc-merge
    Merge changes into the work file.

C-x v h     vc-insert-headers
    Insert headers in a file for use with your version-control system.

C-x v u     vc-revert-buffer
    Revert the buffer and the file to the working revision from which you started editing the file.
   
C-x v c     vc-rollback
    Remove the last-entered change from the master for the visited file. This undoes your last check-in.

M-x vc-find-conflicted-file

M-x vc-resolve-conflicts
    pop up an ediff-merge session on a file with conflict markers



[ VC Directory Commands ]
-------------------------

Up- and down-arrow keys
    move in the buffer;
   
n and p
    also move vertically as in other list-browsing modes.

<SPC> and <TAB>
    behave like down-arrow

<BackTab>
    behaves like up-arrow.

o    visits that file in another window.

q    dismisses the directory buffer.

f    visit the file on the current line.

C-m    Same with above

x    hides up-to-date files.

m    marks the file or directory on the current line. If the region is active, m marks all the files in the region. There are some restrictions when marking: a file cannot be marked if any of its parent directories are marked, and a directory cannot be marked if any files in it or in its child directories are marked.

M    marks all the files with the same VC state as the current file if the cursor is on a file. If the cursor is on a directory, it marks all child files. With a prefix argument: marks all files and directories.

u    unmarks the file or directory on the current line. If the region is active, it unmarks all the files in the region.

U    marks all the files with the same VC state as the current file if the cursor is on a file. If the cursor is on a directory, it unmarks all child files. With a prefix argument: unmarks all marked files and directories.


* It is possible to do search, search and replace, incremental search, and incremental regexp search on multiple files. These commands will work on all the marked files or the current file if nothing is marked. If a directory is marked, the files in that directory shown in the VC directory buffer will be used.

S    searches the marked files.

Q    does a query replace on the marked files.

M-s a C-s
    does an incremental search on the marked files.

M-s a C-M-s
    does an incremental regular expression search on the marked files.

* Commands are also accessible from the VC-dir menu. Note that some VC backends use the VC-dir menu to make available extra, backend-specific, commands. For example, Git and Bazaar allow you to manipulate stashes and shelves. (These provide a mechanism to temporarily store uncommitted changes somewhere out of the way, and bring them back at a later time.)

* Normal VC commands with the C-x v prefix work in VC directory buffers. Some single-key shortcuts are available as well; =, +, l, i, and v behave as through prefixed with C-x v.

The command C-x v v (vc-next-action) operates on all the marked files.

When C-x v v (vc-next-action) operates on multiple files, all of those files must be either in the same state or in compatible states (added, modified and removed states are considered compatible). Otherwise it signals an error. This differs from the behavior of older versions of VC, which did not have fileset operations and simply did vc-next-action on each file individually.

If any files are in a state that calls for commit, C-x v v reads a single log entry and uses it for the changeset as a whole. If the underling VCS is file- rather than changeset-oriented, the log entry will be replicated into the history of each file.



[ In '*vc-change-log* ]
-----------------------

p    Move to the previous revision-item in the buffer. (Revision entries in the log buffer are usually in reverse-chronological order, so the previous revision-item usually corresponds to a newer revision.) A numeric prefix argument is a repeat count.

n    Move to the next revision-item (which most often corresponds to the previous revision of the file). A numeric prefix argument is a repeat count.

P    Move to the log of the previous file, when the logs of multiple files are in the log buffer (see VC Directory Mode). Otherwise, just move to the beginning of the log. A numeric prefix argument is a repeat count, so C-u 10 P would move backward 10 files.

N    Move to the log of the next file, when the logs of multiple files are in the log buffer (see VC Directory Mode). It also takes a numeric prefix argument as a repeat count.

a    Annotate the revision indicated by the current line.

e    Modify the change comment displayed at point. Note that not all VC systems support modifying change comments.

f    Visit the revision indicated at the current line, like typing C-x v ~ and specifying this revision's ID (see Old Revisions).

d    Display the diff (see Comparing Files) between the revision indicated at the current line and the next earlier revision. This is useful to see what actually changed in the file when the revision indicated on the current line was committed.

D    Display the changeset diff (see Comparing Files) between the revision indicated at the current line and the next earlier revision. This is useful to see all the changes to all files that the revision indicated on the current line did when it was committed.


   
[ VC-Annotate menu ]
--------------------

From the annotate buffer, these and other color scaling options are available from the ‘VC-Annotate’ menu. In this buffer, you can also use the following keys to browse the annotations of past revisions, view diffs, or view log entries:

p    Annotate the previous revision, that is to say, the revision before the one currently annotated. A numeric prefix argument is a repeat count, so C-u 10 p would take you back 10 revisions.

n    Annotate the next revision—the one after the revision currently annotated. A numeric prefix argument is a repeat count.

j    Annotate the revision indicated by the current line.

a    Annotate the revision before the one indicated by the current line. This is useful to see the state the file was in before the change on the current line was made.

f    Show in a buffer the file revision indicated by the current line.

d    Display the diff between the current line's revision and the previous revision. This is useful to see what the current line's revision actually changed in the file.

D    Display the diff between the current line's revision and the previous revision for all files in the changeset (for VC systems that support changesets). This is useful to see what the current line's revision actually changed in the tree.

l    Show the log of the current line's revision. This is useful to see the author's description of the changes in the revision on the current line.

w    Annotate the working revision–the one you are editing. If you used p and n to browse to other revisions, use this key to return to your working revision.

v    Toggle the annotation visibility. This is useful for looking just at the file contents without distraction from the annotations.

C-c C-c comment out marked area

More general (I guess)
M-x outline-minor-mode collapses function definitions in a file to a mere {...}
M-x show-subtree If you are in one of the collapsed functions, this un-collapses it

In order to achive some of the feats coming up now you have to run etags *.c *.h *.cpp (or what ever ending you source files have) in the source directory
M-. (Thats Meta dot) If you are in a function call, this will take you to it's definition
M-x tags-search ENTER Searches through all you etaged
M-, (Meta comma) jumps to the next occurence for tags-search
M-x tags-query-replace yum. This lets you replace some text in all the tagged files

[GDB (Debugger)]
M-x gdb starts up gdm in an extra window

[Version Control]
C-x v d show all registered files in this dir
C-x v = show diff between versions
C-x v u remove all changes since last checkin
C-x v ~ show certain version in different window
C-x v l print log
C-x v i mark file for version control add
