I am using the PHPstorm IDE (java software, run with oracle java 7) which defines the shortcuts Ctrl+F12 and Alt+F8 which are not working.

Other shortcuts do work, so I think there might be some kind of shortcut conflict wit XFCE.

Actually nothing (no XFCE action) is happening when pressing one of these combos.

Under Settings -> Keyboard -> Application Shortcuts none of this shorts is used.

Are there any other places which could cause shortcut problems?

Look in the Window Manager settings, Keyboard tab. That has more keyboard shortcuts in addition to the ones in the keyboard application shortcuts.

On my XFCE config (xubuntu 12.10), Alt+F8 is assigned to "Stick window". Ctrl+F12 is assigned to "Workspace 12".
