Feature Request -- RESTORE_FROM_TRAY-shortcut

[am2del]

Allow user to select a RESTORE_FROM_TRAY shortcut. Partially for the lazy, but also for the multi-monitor user who has the screen with tray switched off.

Also, in order to ensure shortcuts doesn't interfere with other DE/WM shortcuts - user should be able to set a "free" key combination - like those already existing for pop-up dictionaries.

Is there no way to add a system shortcut on Linux to start programs? Since starting zkanji again will just restore the original running one, this would be a better local solution. The popup dictionaries needed a shortcut since the point of them is to be able to access them fast and then let them disappear again, but it's not typical for programs to have a shortcut restoring them from the tray or the task bar.
