[Users] Shortcut key to fancy render view for HTML messages

[flyingrhino]

The "a" key moves to the next part -- keep hitting it as required (it
wraps back to the first part).  The "z" key goes to the previous part;
but does not wrap to the last part.

My apologies, there was a lot of junk mail yesterday and I must have deleted your response with it.
Yes, your response is exactly what I've been looking for.
Thank you very much.

Now that I know what to look for - it does appear in the menus (View -> Go To -> Next part A / Previous part Z) , but the name "part" is not descriptive - especially since the column is named "MIME Type" if you expand it horizontally :(

Anyway problem solved !
