stuebinm 6afb255d97 nixos: remove all uses of lib.mdDoc
these changes were generated with nixq 0.0.2, by running

  nixq ">> lib.mdDoc[remove] Argument[keep]" --batchmode nixos/**.nix
  nixq ">> mdDoc[remove] Argument[keep]" --batchmode nixos/**.nix
  nixq ">> Inherit >> mdDoc[remove]" --batchmode nixos/**.nix

two mentions of the mdDoc function remain in nixos/, both of which
are inside of comments.

Since lib.mdDoc is already defined as just id, this commit is a no-op as
far as Nix (and the built manual) is concerned.

Whether to enable the {command}`actkbd` key mapping daemon.
Turning this on will start an {command}`actkbd`
instance for every evdev input that has at least one key
(which is okay even for systems with tiny memory footprint,
since actkbd normally uses \<100 bytes of memory per
instance).
This allows binding keys globally without the need for e.g.
X11.

description = ''
Key bindings for {command}`actkbd`.
See {command}`actkbd` {file}`README` for documentation.
The example shows a piece of what {option}`sound.mediaKeys.enable` does when enabled.
