Quick OS X (and Emacs) Keystroke Reference
Emacs keystrokes supported by all OS X applications that use native text widgets.
|ctrl-A||Moves your insertion point to the beginning of the paragraph.||A = beginning of the alphabet.|
|ctrl-E||Deposits your insertion point at the end of the paragraph.||E = End.|
|ctrl-D||Forward delete. (Deletes the letter to the right of the insertion
|D = Duh, you're an idiot|
|ctrl-K.||Instantly deletes all text from the insertion point to the right
end of the line.
|K = Kills the rest of the line.|
|ctrl-O||Inserts a paragraph break, much like Return, but leaves the insertion
point where it was, above the break. This is the ideal trick for
breaking a paragraph in half when you've just thought of a better
ending for the first part.
|O = Not Sure|
|ctrl-T||Moves the insertion point one letter to the right--and along with it,
drags whichever letter was to its left.
|T = Transpose letters.|
|option-delete||Deletes the entire word to the left of the insertion point. When
you're typing along in a hurry, and you discover that you've just
made a typo, this is the keystroke you want. It's much faster to
nuke the previous word and retype it than to fiddle around with the
mouse and the insertion point just to fix one letter.
|ctrl-B, ctrl-F||Moves the insertion point one character to the left or right, just
like the left and right arrow keys.
|B = Back, F = Forward.|
|ctrl-N, ctrl-P||Moves the insertion point one row down or up, like the down and up
|N = Next, P = Previous.|
