clutch_mode_toggle
Flips the value of cl_clutch_mode each time it runs — one call turns it on, the next call turns it off. A single bound key can handle both states, instead of needing two separate binds for true and false.
Examples
clutch_mode_toggle - Switches clutch mode on if it is off, and off if it is on.
bind "h" "clutch_mode_toggle" - Pressing H toggles clutch mode.
