The drivers subsystem provides all the basic services needed to realize an

Most importantly, the driver manager reports the available block devices.
As user input may enter the system in multiple ways - most prominently PS/2
and USB HID - the drivers subsystem contains a so-called input-filter
and USB HID - the drivers subsystem contains a so-called event-filter
component that merges these event streams and applies transformations like
key remappings or mouse acceleration.

By default, Sculpt uses the US-English keyboard layout with a functioning
capslock key. You may possibly want to adjust the former and - as a Vim
user - most likely discharge the latter. As mentioned in Section
[Drivers subsystem], user input is processed by the input-filter component.

You can edit this component's configuration via

"de_de.chargen" and save the file. The change becomes effective immediately at

Take the time to review the remaining parts of the input-filter
Take the time to review the remaining parts of the event-filter
configuration. The nested configuration nodes define a hierarchy of
filters that are applied in the order from the inside to outside
(Figure [input_filter]). There are filters for merging events ('<merge>'),
