I have the top-left corner on MacOS set to act as a "hot corner." Whenever my mouse goes there, it triggers exposé, showing all my windows to me. I got the habit from using gnome3, which does this by default, and find it quite handy with muscle memory.

There are three other corners as well! I have one as show other windows from the same app, one as show windows on this desktop, and one for show all desktops. actually leave top left unhot because that's where the apple menu is.

I use the top-left corner in macOS for "Disable screensaver." When I'm pondering something on the screen for a while, I can just move the mouse there and not be interrupted.

When I use my Windows machine, it's probably the feature I miss most. I've asked my IT people at work, and they tell me there's no way to disable the screen saver on demand in Windows. I don't know if that's an OS thing, or just one of their policies.

Conversely, Option-top right corner activates the screen saver.

on MacOS, caffeine is a good tool but if you need it in dock (pill?) form, the amazing Amphetamine app is there for you. It'll even (if you use safari) keep you up just long enough to finish that big download. https://apps.apple.com/us/app/amphetamine/id937984704?mt=12

on Windows, the process involves taking a Power Request. A Display power request keeps the display awake, and is the overriding above most all else. It's trivial to do with a little PowerShell ( https://blog.backslasher.net/windows-awake-ps.html ) though the fine folks at Microsoft have included it in their standard set of PowerToys as Awake: https://learn.microsoft.com/en-us/windows/powertoys/awake

Last I remember, this keeps you from having a screensaver come up.

Normally Windows apps can call SetThreadExecutionState to request the screensaver not come on. Video players do this, as do some other apps. See here[1] for a Powershell script that does just this, for example.

I suppose they could have deployed some group policy that disables this behavior. That'd be annoying if it's the case.

There is SOME way to disable the screensaver, because you can play a movie and the screensaver doesn't come on.

So poke around.

"caffeine -imdsu" in the terminal seems to work very well for that purpose.

My top right is "lock screen", which is a handy gesture I can make when getting up.

My bottom left is that, very handy indeed.
