My contribution to the current key-clicker fidget craze: a two-key clicker where one is a modifier key. So you can type to ctrl/cmd-Z to undo in your real life.

No guarantees it will work, but you can try as much as you want! 😉

Modifier (Undo) Keyboard Clicker - Free 3D Print Model - MakerWorld

Download this free 3D print file designed by Geekman. There's no undo in real life, but with this key clicker, you can try as much as you want! This is a keyboard clicker that lets you to install a 1.25u modifier key alongside a standard 1u keycap. This allows for classic shortcut combinations such as ctrl-z (undo) or ctrl-s (save). For Mac users, Cmd keys work too!AssemblyWhen installing keyswitches, remember that the modifier (longer key) is on the left, and the keyswitches have pins towards the bottom. Real keycaps aren't cubes, so you need to orient your keyswitches correctly. AttributionThis model is a modification of the clicker by Hartman 3D Designs. (see sidebar)
