Paul,

My 4k, 40" monitor swings on an absurdly long/high monitor arm,
over my bed. I'm lying down now, in bed, as I write this.
The monitor is at arms length, for a kind of IMAX experience.

When I hit a certain hotkey my code turns the monitor off.
Hitting the same (global) hotkey ( assigned to a mouse button )
turns the monitor back on again. The mouse button:

At night, in a dark room, when I'm trying to sleep, movement jiggles
the mouse, briefly turning the monitor back on again (yikes!);

Put the mouse upside down :-)
