I'm running Natty with a clean install on a MacBook Pro (with no OSX install) and currently loving the switch! I found the area in keyboard layout options to map ctrl to the win keys (and the usual ctrl keys) and that turned my command key into a ctrl key which I'm used to from mac osx (working perfectly yesterday.)

However, now when I try, it's not working and the settings are still the same... I've tried to add different keyboards (worked with my original Canada English default yesterday... tried US Macintosh and set Keyboard Model to MacBook Pro (both regular and intl, neither worked.)

It was really weird because for a second my right command key was working as expected but not the left, and now neither are working.

Any thoughts or suggestions would be greatly appreciated.

I have the same issue. – zookalicious May 13 '11 at 13:29

Figured it out! The default of having the Dash set to the Mod4 key (Command key) apparently causes several problems (aside from annoying me).

I solved this problem by changing the key that triggers the Dash from the Command (Mod4) key to something else. In my example I used the F1 key but I think any single key should be fine.

Simply type the following in a terminal to change the Dash from Mod4 to F1.

 gconftool --set /apps/compiz-1/plugins/unityshell/screen0/options/show_launcher --type=string "F1"

Now when you select "map ctrl to the win keys (and the usual ctrl keys)" it should work as expected! And if you need access to the dash you can activate it by hitting the F1 key, 4-finger tapping the trackpad (on devices that support it), or clicking the ubuntu logo in the top left.

(Note: I am using Unity 3D)
