Question keyboard with the key depth/key travel of a laptop?

The best way would be to look at what switches match your description and either buy a KB that has them or buy one that lets you swap the switches in... such as the one I got yesterday that lets me swap caps and switches if I chose to - https://nuphy.com.au/products/halo96-wireless-mechanical-keyboard (not suggesting it, just an example) - their air range might be what you were after

Logitech G915 might match that description - https://www.logitechg.com/en-au/pro...file-wireless-mechanical-gaming-keyboard.html
