## Usage
|
|
|
|
|
|
|
|
|
|
To open the UI to modify the mappings, look into your applications menu
|
|
|
|
|
and search for 'Key Mapper' in settings. You can also start it via
|
|
|
|
|
`key-mapper-gtk`. It works with both Wayland and X11.
|
|
|
|
|
|
|
|
|
|
If stuff doesn't work, check the output of `key-mapper-gtk -d` and feel free
|
|
|
|
|
to open up an issue here.

## Macros
|
|
|
|
|
|
|
|
|
|
It is possible to write timed macros into the center column:
|
|
|
|
|
- `k(1).k(2)` 1, 2
|
|
|
|
|
- `r(3, k(a).w(500))` a, a, a with 500ms pause
|
|
|
|
|
- `m(Control_L, k(a).k(x))` CTRL + a, CTRL + x
|
|
|
|
|
|
|
|
|
|
Documentation:
|
|
|
|
|
- `r` repeats the execution of the second parameter
|
|
|
|
|
- `w` waits in milliseconds
|
|
|
|
|
- `k` writes a single keystroke
|
|
|
|
|
- `m` holds a modifier while executing the second parameter
|
|
|
|
|
- `.` executes two actions behind each other
|
|
|
|
|
|
|
|
|
|
For a list of supported keystrokes and their names, check the output of
|
|
|
|
|
`xmodmap -pke`
|
|
|
|
|
|
|
|
|
|
## Installation
|
|
|
|
|
|
|
|
|
|
After your installation, independent of the method, you should add yourself
|
|
|
|
|
to the `input` and `plugdev` groups so that you can read keycodes from them.
|
|
|
|
|
You have to start the application via sudo otherwise.
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
sudo usermod -a -G plugdev,input $USER
|
|
|
|
|
# log out and back in or restart, the two groups should be visible with:
|
|
|
|
|
groups
|
|
|
|
|
```
|
