ok, on my "old" computer (source computer), I found two files in /Users/Somian/Library/Preferences:
de.wengenmayer.Cheetah3D.LSSharedFileList.plist
de.wengenmayer.Cheetah3D.plist
I put them in put the files in /Users/Somian/Library/Preferences (the username on my new computer is the same).
When I started cheetah 3D, however and go to preferences, for some reason the keys aren'y bound like that.
For example, I assigned the number keys to the various selection mode. (see attached screenshot).
On my new computer, this still comes up empty.
I checked the plist file, however, and it does contain information about the key bindings (second screenshot), so I'm wondering why it doesn't work.
