A set of values to be modified by {command}`kwriteconfig5`.
|

|
|
|

The example value would cause the following command to run in the
|
||
|
|
activation script:
|
||
|
|
|
||
|
|
``` shell
|
||
|
|
kwriteconfig5 --file $XDG_CONFIG_HOME/powermanagementprofilesrc \
|
||
|
|
--group AC \
|
||
|
|
--group HandleButtonEvents \
|
||
|
|
--group lidAction \
|
||
|
|
--key lidAction \
|
||
|
|
32
|
||
|
|
```
|
