The force needed to register a key; lower is lighter to type on.
Swap switches without soldering.
Registers every simultaneous keypress.
Set the actuation point per key (analog / Hall-effect boards).
Keys report their travel depth for variable gamepad-style input and multi-stage actions.
Performance
How often the keyboard reports input; higher can reduce latency.
End-to-end keypress latency over a wired connection; lower is better.
End-to-end keypress latency over the fastest wireless mode; lower is better.
Resets a key dynamically as it moves, enabling faster repeated inputs.
Layout & size
