Currently, you can jump to the end of the longest clip in a session (ctrl+end). It would be nice if you could also have the option to jump to the end of a selected clip.
If there is already a way to assign a keyboard shortcut to do this, I have been unable to find it searching Google or flipping through the help and the Sonar X1 Power! book (currently using Platinum, sometimes features get mentioned in older versions and never mentioned again).
