How do I bring back Xbench with a hot key on a MacBook Air?

I just installed the latest version of XBench 3.0 on my MacBook Air that runs Win 7.

However, after I close the Xbench window, I can’t figure out how to open it because the MacBook Air does not have the Insert key so I cannot use Ctrl+Alt+Insert.

What can I do to bring back Xbench with a hot key?

Just go to Tools > Settings > Layout & Hotkeys and change the Source Hotkey to another keyboard shortcut that suits your keyboard.
