Great addon but needs choice of keyboard shortcut Rated 4 out of 5 stars

Great addon thankyou.
I am using firefox addon Custom Buttons
and many of the buttons use Shift+RightClick to open the buttons menu for many functions.
I need to be able to set Element Inspector to Ctrl+RightClick or something else.
Possible for the Option please?

Without the option then I am regretfully unable to use this addon.
