I'm trying to set my numpad to be a media control centre. I want to have the 0 key pull up Clementine and bring it to the foreground. Right now I have it set to launch Clementine, but it just dances in the launcher and doesn't come to the foreground. So, I have Clementine pinned to the second slot on the launcher, and I want to set up a custom key shortcut via the Keyboard Settings. The question is, how do I send Super+2 as a command?

Second, I want the plus and minus keys to send Alt + Left and Alt + Right (for browser navigation).

Third, and less important, I want the period key to open Clementine's EQ, and 7 and 9 to send Fast Forward and Rewind.
