Modifiers are the special keyboard keys: _shift_, _alt_, _control_ & _GUI_. Their keycodes can be found in the [list of codes](./list-of-codes.mdx#modifiers).
|
|
Modifiers can be used both as [keys](#modifier-keys) and as [functions](#modifier-functions).
|
|
|
|
### Modifier Keys
|
|
|
|
These act like any other key code.
|
|
|
|
- e.g. `&kp LEFT_GUI` pushes and releases the left GUI key.
|
|
|
|
### Modifier Functions
|
|
|
|
Modifier functions add one or more modifiers to a code.
|
|
|
|
These functions take the form: `XX(code)`
|
|
|
|
- Modifier functions apply a modifier to a code:
|
|
- `&kp LS(A)` = `LEFT_SHIFT`+`A` (a capitalized **A**).
|
|
- They can be combined:
|
|
- `&kp LC(RA(B))` = `LEFT_CONTROL`+`RIGHT_ALT`+`B`
|
|
- They can be applied to a modifier keycode to create combined modifier keys:
|
|
- `&kp LS(LALT)` = `LEFT_SHIFT` + `LEFT_ALT`
|
|
- Some basic codes already include a modifier function in their definition:
|
|
- `DOLLAR` = `LS(NUMBER_4)`
|
|
- There are left- and right-handed versions of each modifier (also see [table in the list of codes](./list-of-codes.mdx#modifiers)):
|
|
- `LS(x)`, `LC(x)`, `LA(x)`, `LG(x)`, `RS(x)`, `RC(x)`, `RA(x)`, `RG(x)`
|
|
- Modified keys can safely be rolled-over. Modifier functions are released when another key is pressed.
|
|
- Press `&kp LS(A)`, then press `&kp B`, release `&kp LS(A)` and release `&kp B` results in **Ab**. Only the A is capitalized.
