Shout out to this free, open source project Dual Monitor Tools.
I often have my ThinkPad connected to an external monitor, and recently I’ve needed to move the mouse cursor across the two screens back and forth regularly – that is a lot of traversing!
So a search on whether I can ‘teleport’ the cursor from one screen to another using a keyboard shortcut resulted in Dual Monitor Tools. And it works brilliantly!
Don’t get scared by the amount of features; just use the DMT Cursor tool to add shortcut keys for how cursors operate. I use ‘Win + z’ as the shortcut key to ‘Move cursor to next screen’ – which is the ‘teleport’ feature I was looking for – and I also have ‘Cursor movement between screen is sticky’ as default so there’s a bit of resistance when manually traversing between screens (and hence precision at the monitor edges).
