Keyboard shortcut for Marker List

[Matthew]

I made a tiny PR to add a keyboard shortcut for the Marker List. Following the pattern of other recent List shortcuts, it's Ctrl+M.

I noticed that none of the new Lists are listed in the keyboard shortcuts help page. Is this because it's policy not to include shortcuts that are specific to one pakset, or it just that nobody has remembered to do it yet?

Thank you for that - now incorporated.

As to the help files, there is no policy to exclude keyboard shortcuts, so I rather suspect that it is for the latter reason that they have not been included.
