# Leader Key
|
|
The leader key acts as a prefix to a key sequence. These can be used to trigger macros quickly
|
|
without dedicated keys set to each function. For those of you who dislike key combos, such as
|
|
Ctrl+Shift+Esc, then this feature is for you. This is very much inspired from vim.
|
|
|
|
Leader key sequences can be as long or short as you like. The action must be a macro, so it
|
|
can be things like unicode macros, or generic macros. The example below shows how you would
|
|
trigger task manager in Windows with a leader sequence.
|
|
|
|
1. Assign a key to KC.LEAD
|
|
2. Above your keymap, include a LEADER_DICTIONARY.
|
|
|
|
```python
|
|
from kmk.macros.simple import simple_key_sequence
|
|
|
|
# ...
|
|
|
|
keyboard.leader_dictionary = {
|
|
(KC.T, KC.A, KC.S, KC.K): simple_key_sequence([Modifiers.KC_LCTRL(Modifiers.KC_LSHIFT(Common.KC_ESC))])
|
|
}
|
|
|
|
keymap = [...KC.LEAD,...]
|
|
|
|
# ...
|
|
```
|
|
|
|
If defining tuples of keycodes is too obtuse for you, we have a convenience
|
|
function available for that, too!
|
|
|
|
```python
|
|
from kmk.keycodes import generate_leader_dictionary_seq as glds
|
|
|
|
# ...
|
|
|
|
keyboard.leader_dictionary = {
|
|
glds('task'): simple_key_sequence([Modifiers.KC_LCTRL(Modifiers.KC_LSHIFT(Common.KC_ESC))])
|
|
}
|
|
|
|
# ...
|
|
```
|
|
|
|
# Modes
|
|
1. LeaderMode.TIMEOUT (the default)
|
|
2. LeaderMode.ENTER
|
|
|
|
### Timeout Mode
|
|
Will expire after a timer and trigger the sequence that matches if any.
|
|
This can be enabled with
|
|
```python
|
|
from kmk.consts import LeaderMode
|
|
keyboard.leader_mode = LeaderMode.TIMEOUT
|
|
```
|
|
|
|
The timeout can be set like this
|
|
```python
|
|
keyboard.leader_timeout = 2000 # in milliseconds-ish
|
|
```
|
|
|
|
The timeout defaults to `1000`, which is roughly a second.
|
|
|
|
### Enter Mode
|
|
Has no timeout. To end sequence press the enter key, or cancel and do nothing, press escape.
|
|
This can be enabled with
|
|
|
|
```python
|
|
from kmk.consts import LeaderMode
|
|
keyboard.leader_mode = LeaderMode.ENTER
|
|
```
