Keyboard gestures - Factor Documentation (original) (raw)

There are two types of keyboard gestures:
key-down
key-up

Each keyboard gesture has a set of modifiers and a key symbol. The set modifiers is denoted by an array which must either be f, or an order-preserving subsequence of the following:

{ S+ C+ A+ M+ }

S+
C+
A+
M+

A key symbol is either a single-character string denoting literal input, or one of the following strings:

The S+ modifier is only ever used with the above action keys; alphanumeric input input with the shift key is delivered without the S+ modifier set, instead the input itself is upper case. For example, the gesture corresponding to s with the Control and Shift keys pressed is presented as

T{ key-down f { C+ } "S" }

The RET and TAB keys are never delivered in their literal form ("\n" and "\t").
