how do i make an autohotkey v2 script that holds the CTRL key?

ive tried endless amounts of examples scripts ive found online but none work on autohotkey v2.

im playing a game that requires me to hold control to jump but its hurting my finger. Ideally i want to press a shortcut like Shift + ` or double click the control key and have it leave the control key pressed until i toggle it off with the same shortcut or double pressing control.
