I use Nano as my editor of choice, having decided to be Switzerland in the vi/emacs wars. However, when I upgraded to OSX Lion recently, I found the cursor jumped all over the place when editing text. This is obviously suboptimal. Luckily, it’s easy to fix. Change
xterm-color in the settings.
You may need to do this for every style of window using
xterm-256color just to make sure, but that should be it.
