C = Control

M = Meta = Alt|Esc

Basics Basic movement

C-x C-f "find" file i.e. open/create a file in C-f forward char
buffer C-b backward char
C-x C-s save the file C-p previous line
C-x C-w write the text to an alternate C-n next line
name M-f forward one word
C-x C-v find alternate file M-b backward one word
C-x i insert file at cursor position C-a beginning of line
C-x b create/switch buffers C-e end of line
C-x C-b show buffer list C-v one page up
C-x k kill buffer M-v scroll down one page
C-z suspend emacs M-< beginning of text
C-X C-c close down emacs M-> end of text

Editing Important
M-n repeat the following command n C-g quit the running/entered command
times C-x u undo previous action
C-u repeat the following command 4 M-x revert-buffer RETURN (insert like
times this) undo all changes since last save
C-u n repeat n times M-x recover-file RETURN Recover text
C-d delete a char from an autosave-file
M-d delete word M-x recover-session RETURN if you
M-Del delete word backwards edited several files
C-k kill line Online-Help
C-Space Set beginning mark (for region C-h c which command does this
marking for example) keystroke invoke
C-W "kill" (delete) the marked region C-h k which command does this
region keystroke invoke and what does it do?
M-W copy the marked region C-h l what were my last 100 typed keys
C-y "yank" (paste) the copied/killed C-h w what key-combo does this
region/line command have?
M-y yank earlier text (cycle through kill
C-h f what does this function do
buffer) C-h v what's this variable and what is it's
C-x C-x exchange cursor and mark value
C-h b show all keycommands for this
C-t transpose two chars buffer
M-t transpose two words C-h t start the emacs tutorial
C-x C-t transpose lines C-h i start the info reader
M-u make letters uppercase in word from C-h C-k start up info reader and go to a
cursor position to end certain key-combo point
M-c simply make first letter in word C-h F show the emacs FAQ
uppercase C-h p show infos about the Elisp package
M-l opposite to M-u on this machine
 Search/Replace with regular
Search/Replace expressions
Characters to use in regular
C-s Search forward expressions:
C-r search backward
C-g return to where search started (if ^ beginning of line
you are still in search mode) $ end of line
M-% query replace . single char
Space or y replace this occurence .* group or null of chars
Del or n don't replace \< beginning of a word
. only replace this and exit (replace) \> end of a word
, replace and pause (resume with Space [] every char inside the backets (for
or y) example [a-z] means every small letter)
! replace all following occurences M C-s RETURN search for regular
^ back to previous match expression forward
RETURN or q quit replace M C-r RETURN search for regular
expression backward
Window-Commands M C-s incremental search
C-s repeat incremental search
C-x 2 split window vertically M C-r incremental search backwards
C-x o change to other window C-r repeat backwards
C-x 0 delete window M-x query-replace-regexp search and
C-x 1 close all windows except the one replace
the cursors in
C-x ^ enlarge window
M-x shrink-window command says it ;-)
M C-v scroll other window
C-x 4 f find file in other window
C-x 4 o change to other window
C-x 4 0 kill buffer and window
C-x 5 2 make new frame
C-x 5 f find file in other frame
C-x 5 o change to other frame
C-x 5 0 close this frame
 Bookmark commands
Programming C-x r m set a bookmark at current cursor
M C-\ indent region between cursor and pos
mark C-x r b jump to bookmark
M-m move to first (non-space) char in M-x bookmark-rename says it
this line M-x bookmark-delete "
M-^ attach this line to previous M-x bookmark-save "
M-; formatize and indent comment C-x r l list bookmarks
C, C++ and Java Modes d mark bookmark for deletion
M-a beginning of statement r rename bookmark
M-e end of statement s save all listed bookmarks
M C-a beginning of function f show bookmark the cursor is over
M C-e end of function m mark bookmarks to be shown in
C-c RETURN Set cursor to beginning of multiple window
function and mark at the end v show marked bookmarks (or the one
C-c C-q indent the whole function the cursor is over)
according to indention style t toggle listing of the corresponding
C-c C-a toggle modus in which after paths
electric signs (like {}:';./*) emacs does w " path to this file
the indention x delete marked bookmarks
C-c C-d toggle auto hungry mode in Del ?
which emacs deletes groups of spaces q quit bookmark list
with one del-press M-x bookmark-write write all bookmarks
C-c C-u go to beginning of this in given file
preprocessor statement M-x bookmark-load load bookmark from
C-c C-c comment out marked area given file
