How to use...Hot Corners (Mac)

[KevinJS]

There's a useful feature hidden away in macOS that doesn't get half the recognition that it should.

With Hot Corners set up, moving the mouse cursor to the corner of the screen invokes a user-defined function such as immediately starting the screen saver or clearing the screen to the desktop.

To use it, go to System Preferences/Mission Control

Clicking on the Hot Corners... button will allow you to choose from a variety of features:

By default, macOS will assign the Hot Corner to the unmodified mouse cursor. If you want to ensure that a simple movement won't invoke the function, simply hold down one of the modifier keys while you are assigning the corner.

Thanks Kevin, I knew nothing about that.

Hi Kevin - I use Launchpad a lot and have my lower left screen setup as a 'hot corner' to this app - a lot quicker than clicking the icon in the dock - Dave

Hi Dave, I don't use it much. I remembered it when someone on mac-forums.com asked why their screensaver wasn't working during music playback. Figured forcing the screensaver to operate would be the easiest way to sort that problem out. Saves waiting five minutes too.

Thanks, Kevin. Your post was the first time I've heard of hot corners.

By the way, @giradman, I stole your method of annotating images in Preview, so thank you for that information.

I'll probably do another "how to..." at some point concerning this tool, once I've had a chance to look around it.

Hi Kevin - no problem @ all - I've left a lot of posts in the MacForums that seemed to have helped others - still learning more myself (e.g. have done little w/ the PDF features) - an excellent book that's on my iPad is shown below (both available as a Kindle & a iBooks selection) - price seems to be about the same, i.e. $14 (however, would be a better bargain at half that price). Looking forward to your 'tutorial' - Dave
