Emacs, OS X and forward-delete.
I recently moved from Vim to Emacs.
Right away I realized that forward-delete wasn’t working (deleting a character on the right of the cursor, rather than back-spacing).
I know little about Emacs, but figured out, with a tip from Ross, how to map the chord of “Function-Backspace” to forward-delete.
Add this to your .emacs file:
(global-set-key [kp-delete] 'delete-char)
Simple but a requirement for coding.
