Description
Adds a function called togglepointerconstraints to turn pointer constraint enforcement on and off with a keybind.
Usage
Add a binding for the togglepointerconstraints function in the keys[] array of config.h. The function does not take any argument. Pointer constraints default to enabled, and can be toggled on and off with the function from there.
Example:
{ MODKEY, XKB_KEY_c, togglepointerconstraints, {0}},
