Lock mouse cursor to current monitor except while hotkey is held down

Return to DisplayFusion Scripted Functions (Macros)

Description	This is an implementation of the requested feature on the forums of having the mouse cursor locked to the current monitor, except while a hotkey is held down. This function combines the locking function with the unlocking function: Pressing and releasing this function's hotkey locks the mouse to the current monitor. It's then kept locked until you *press and hold down* the hotkey. While it's held down you can freely move between monitors. Once released, it gets locked again to the new current monitor.
