:( I supposed that. It will be hard to have such a functionality in
xterm then. And no other terminal works completely fine with emacs for
me.

Users and external developers may try their best it this annoys them
enough.

On tty the F10 menu opens in the minibuffer. It would be better if we
can just show the same menu than with the mouse instead, because it
appears in place, closer to where the user is editing. And the
experience is a bit more consistent IMHO.

But context menu it more mouse-oriented in general because it is a need
specially for more mouse oriented users. Why to do something like F10 +
arrow + arrow + Enter: when you can do just M-w? Or why to use arrows if
just used the mouse to activate the menu?
