How to remap Super_L as something else ?

[rpringadi]

Thanks for this amazing tool. Question, how do I remap Super_L as something else?

I pressed the capture button (for remapping), I press Super_L, instead of capturing that key (the Super_L), the desktop opens the menu.

I'm currently using Linux Mint - xfce desktop
