quick mark/unmark mod checkbox

[junhinhow]

TL;DR

implement a hotkey for fast mark/unmark checkbox (i guess that really even already been done, but i was not able to find on google or forums... so...)

What/Why ???

as the title says, is just a function like on press SPACE (the most comom hotkey for that, or can be any other, no problem) the yellow marked box of mod in the mod-menu-selection should be mark (or if already marked, unmark) for fast enable disable mods by keyboard (much faster than mouse for big mods like, PY, Bobs, Angels, etc... its so painful mark they all by mouse), especially when you are testing whats gonna be your ideal setup for a new game!
