Dear Maintainer,

   * What led up to the situation?
        - USB Mouse plugged in
        - Mouse&Trackpad settings opened
        - Navigated with tabulator through the menupoints until reaching the
on/off bool button
        - Used Enter to switch to off
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
        - Using tabulator to jump out of the option (I thought it needs to
update the option at least at that point, but no cigar)
        - I clicked the button instead which solved the issue
        - I checked other options (for example in sound settings buttons would
work with enter)
   * What was the outcome of this action?
        - Button switched to "off"
        - Touchpad not disabled (therefore wrong visual feedback)
   * What outcome did you expect instead?
        - Touchpad beeing disabled
        - Correct visual feedback (button state)

Please do not hesitate to tell me what I did wrong (guidelines, procedure,
etc)! I am willing to learn.
