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
```
Note, `null` values will delete the corresponding entry instead of
inserting any value.
