EZ> It's much easier to do "C-u RET" on the top line of the call-tree.

NP> You can use the prefix argument to profiler-report-toggle-entry (C-u

Yes, I see that now.  I don't think it's very obvious, though.

For some reason, we've dedicated all of these keys to this
command: `mouse-1', `i', `TAB', `RET', and we've put it in
the menu-bar menu.  (Why so many keys?)

And yet we've dedicated no key to doing directly what `C-u i'
does.  Maybe that should be rethought?

At the very least, maybe that action should be added to the
menu-bar menu, so that users can more easily discover that
they can invoke it using `C-u i'.
