> Hi, I just wanted to mention that display-local-help (C-h .) does not necessarily provide help that is useful to a user not using a mouse. E.g., in a Gnus Article buffer, if you move point over an attachment button (gnus-header-content face), and run display-local-help, it will tell you "mouse-2: toggle the MIME part; down-mouse-3: more options". A mouse user can right click and get a large menu of commands that can be applied to that MIME part.

It is not the purpose of this command to replace the context menu.
The purpose is to show either the button help (which is what you cite)
or the help-echo text.

> Maybe I am suppose to know how to send a down-mouse-3 without a mouse.

I didn't mean to say that every mouse gesture in Emacs has an
equivalent keyboard command, but in many cases you should be able to
invoke the same command via M-x.

In any case, what you describe now is not related to the original
subject of this bug report.  If you think every mouse gesture in Emacs
should have a keyboard equivalent, please submit a separate
feature-request bug report about that, because it will otherwise be
lost in this bug.

> Or perhaps there is another way to get that menu without a graphical pop-up. I'm interested to learn more.

Look up the command that down-mouse-3 invokes there, then use "C-h w"
to find its other bindings, if any.
