If I'm going to wake up a computer whose monitor is dark, I typically hit the super key, arrow keys, or sometimes the space bar and would never hit Enter as the first key. Why? I remember when people used to just turn monitors off manually before monitor power management, and I remember blank screen savers with first gen energy saving monitors that would turn off if they detected a blank screen. It only takes once where the monitor is off and you hit a key to turn it back on and accidentally confirm some dialog or accept changes or execute a command before you start using keys that don't actually do anything.

I move the mouse, actually the touchpad. It's safer than hitting a key. Then the password prompt appears. Why force us to swype up too? And why up when on phones we swype horizontally, patents?

True, I do favor the mouse. I should have said, "If I'm going to wake up a computer using the keyboard."

That's fair. In my case I have a habit of locking my screen, so that's rarely (if ever) a concern, but I suppose muscle memory is indeed hard to forget.
