I recently installed Rhythmbox, the fantabulous media player using the Gstreamer framework. Nothing personal against the KDE users, but JuK could use adaptive playlisting, and some better tagging support.
On to the problem: My multimedia keys are mapped to F13 thru F21. I use the Play/pause button, the (relabeled) Search and Favorites buttons for going forward one song and back one song. That is, I use them for that in every other media player, and simply disable the khotkeys shortcuts for them.
The problem is, RhythmBox uses ctrl-space for play/pause, ctrl-rightarrow for forward one, and ctrl-leftarrow for back one. How do I make KhotKeys 2 send those key combinations to the Rhythmbox window? As it is, using alt-tab and hitting the keyboard shortcut is insanely time-consuming.
