How can I use Logitech Options to lock my screen with my MX Ergo?

Question

On Windows I'm used to locking my screen via a Logitech Mouse Gesture. Unfortunately, I cannot select "Lock Screen" in the menu on MacOS. Is there still another way to lock the screen?

Given that Logitech Options allows me to launch a specific app, is there an App that I can launch to lock the screen?

Answer 1

In Logitech Options, you can assign a keyboard sequence to a button. For this example, I assigned the top button on the side (the one highlighted in green) the shortcut to lock the screen CommandControlQ.

Now, when I press the button, it's as if I've pressed the keyboard shortcut.

You can do it natively, you don't need Logitech Options to do it for you.

System Prefs > Mission Control > Hot Corners...

You can pick a function for each corner & also define whether you need to be holding a Modifier key while you perform the action [safer for ones that would inconvenience you if done accidentally]

If you hold any Modifier[s] whilst selecting from the drop menu, it will apply it to the gesture.

Then just drag the cursor into the hot corner (optionally whilst holding your chosen modifier[s])
