Make "F" switch between 1 and 2

[dadda]

Hi! I wanted to know if its possible to make my "F" button work as if I would press 1, and if I press it again it's 2 and that it keeps repeating like that? I play fortnite and want a faster way switching shotguns. Thanks!

You're after a simple toggle:f::send % ( ( i:=!i ) ? 1 : 2 )
