Hello, I just found about this, and I think it may be of interest to the readers of this list. If you have trouble with 'j' and 'k' not repeating anymore in OS X Lion, it's because of the new "press and hold" behavior for some keys, which results in a popup being displayed offering accented versions of the letter. Unfortunately Aquamacs does not display this popup, yet the repeat is intercepted by the system. To disable this, you need to type the following in a terminal window: defaults write -g ApplePressAndHoldEnabled -bool NO then restart the applications at least once. Best, Alan
