How do I put Mac Mini to sleep with keyboard only?

Also, my keyboard and mouse are both from Windows machines.

That may complicate the issue. On Mac keyboards with an EJECT key†, pressing CONTROL-EJECT brings up this window:

Single keys activate so you don't need to use the mouse.

R = restart; S = sleep; ESC = cancel; RETURN = shutdown.

I simply do CONTROL-EJECT S to sleep all my Macs for years. If your Win keyboard has an EJECT button, it's worth seeing if it works.

† — those without Touch ID

But if I am done with my Mac Mini, how do I put it to sleep? It sits on a shelf behind a curtain.

I wondered if there was a keyboard shortcut that would do it?

If not, is it just a click of the power button, or does that turn it off?

The fastest and easiest way to Sleep a desktop, is to use the mouse.

Go to the Apple Menu and select Sleep.

Also, my keyboard and mouse are both from Windows machines.

What windows keyboard and mouse do you have?

USB or Wireless with reciever

Most Generic and PC keyboards are not problem.

I use USB Logitech keyboards and mice with several Mac mini's.

When I want to wake the Mac, do I just hit Enter etc... and it will wake, or do I have to put the button again?

To wake the Mac mini, you should be able to hit any key or click the mouse.

I just did it. It is instantly off. And yes I turned off the mouse after.

Again what keyboard and mouse?

The mouse should go into stand-by mode if left on, NO?

Is it the mouse movement that will wake it after, or Keyboard only (which would be better)?

Doesn't matter, either should re-wake the Mac mini.

Yeah' placing the mouse on the charger is going to wake the Mac mini and there is nothing you can do about that.

If the mouse does not hold a charge for more than two or three days, then you should replace it with something more compatible.

You must be very careful not to move the mouse for the first 15 to 30 seconds.
