A named sokol key code, such as W or Space. Input carries the code. Your game decides what a key means.

code : Key -> U16

The sokol key code of a key, as Input carries it.

held : Input, Key -> Bool

True while the key is down. Ask twice in one step and you get the same answer.

pressed : Input, Key -> Bool

True in the first step after the key went down. A key tapped between two steps is pressed but not held.

axis : Input, Key, Key -> F32

1.0 when only pos is held, -1.0 when only neg is held, else 0.0. For example, Key.axis(input, S, W) gives a forward speed.
