in Writer, select some text and format it: hit ~o,h,Enter to open Character; choose FontEffects, hit ~l, ~w, or ~b to change (toggle on/off) the Outline, Shadow or Blinking effect. But ~h does not change Hidden; one must 'confirm' it with the space bar.
Suspect the ~h accelerator of the hidden character attribute is conflicting with the ~h of the help action--but it is an annoying keyboard accelerator inconsistency in the UI.
(In reply to V Stuart Foote from comment #1) > Suspect the ~h accelerator of the hidden character attribute is conflicting > with the ~h of the help action I agree the problem is that ~h is assigned as mnemonic for both "Hidden" and "Help". However the problem can't be easily fixed with a string change, because here ~h is automatically assigned to "Hidden". I submitted a patch https://gerrit.libreoffice.org/c/core/+/106670 to address the symptom of the problem without fixing the underlying flaw of the mnemonic auto-generation mechanism.
