I'm using the XfApplet for integrating the mintMenu into my Mint Xfce installation.
As shortcut I defined Super_L which works fine.
Additionally I want to define a shortcut <Super_L>r to execute gnome-terminal.
Unfortunately the Super_L keystroke gets interpreted and consumed early so that the mintMenu appears and types r into the search field.

Is it possible to configure that both shortcuts Super_L and <Super_L>r work properly?

Edit: This is how the mintmenu looks like.
