Element Hiding Helper shortcut changed abruptly

[Vorpal_Kitten]

For months the shortcut for the 'Select an element to hide' option added by the Element Hiding Helper extension was Ctrl+Alt+Z for me, and now it is Ctrl+Alt+F3 which is both not what my muscle memory is used to and just much harder to hit on the keyboard. Is there an option to set this shortcut yourself that I can use to get it back?

go to about:config
search for
extensions.elemhidehelper.selectelement_key

double click
replace "Accel Shift F3" by "Accel Shift Z"

Oh, thanks!
