Sounds complicated (and I'm not sure it will be possible when we use
GTK tooltips, which is the default in the GTK builds).

Emacs is already capable of redirecting the tooltip text to the echo
area (to see that, disable tooltip-mode), so it should be easy to
provide some command or variable, which, when activated, would copy
the tooltip text to some specialized buffer, where it could be later
read by the user.

Would you like to propose a patch along these lines?

For menus, most Emacs configurations use the toolkit.  Do the toolkits
we use offer capabilities to make the menus "sticky"?

AFAIK, you generally cannot click on tooltips, because they disappear
when you do so.
