Looking at a previous issue, https://github.com/ProseMirror/prosemirror/issues/895, I realized that the keymap in the example setup for undo-ing
Mod-z does not work when caps lock is on.
Based on that issue, it seems that one has to define a
Mod-Z as well. Is there another workaround besides registering
Mod-[lowercase alphabetical] and
Mod-[uppercase alphabetical] repeatedly (maybe by using
prosemirror-keymap to differentiate between a
Mod-Z due to shift-key against a capslock)?
The other thing is that when caps lock is on,
Shift-Mod-z which is the redo command somehow triggers an undo command instead.
On Chrome and Windows 10.
Edit: Oops, forgot to mention I’m seeing this on https://prosemirror.net/.
