== swapping ctrl/caps lock ==
* on osx *
http://ella.slis.indiana.edu/~jfieber/osx/ -- i believe i ended up using ucontrol.
* on ubuntu *
go to System/Settings/Keyboard Preferences (xmodmap is still there if you're so inclined)
also, off the top of my head, it was a pain to:
1. add widgets to the menubar (on ubuntu i just add it)
2. rsync backups to an openbsd server because of the hfs+ tags
3. changing the buttons in Mail.app -- they were horrible
4. shutting down spotlight (can't even remember that one)
5. verbose booting
6. and my personal favorite: getting a cd out of the player when the power is off.
There are answers, I'm sure, to all these questions but you have to figure it out.

ucontrol, and fkeys let you do that. both seem to be unmaitained though.
