Take a look at Helldivers 2 keybinding menu:

Image (collapsible)

It has input types!! Currently present:

• Tap. Triggers only when a button is pushed down and released quickly.
• Double Tap. Triggers on the second press if you quickly push down the same button twice.
• Press. Triggers as soon as a button is pushed down.
• Long press. Triggers after a button has been pushed down for a set amount of time.
• Hold. Triggers continuously while a button is being pushed down.

Would love to see this in your mod!

This is usually implemented by the mod that actually uses the keybindings. Out of scope, but yes it's an excellent idea. I'll close and pin :D
