Most GUI terminal emulators have a preference option to refrain from
squatting important key combinations (F1, F10, Alt+F, Alt+E, …) for
their own UI and pass them to the application running within, although
that runs against keyboard accessibility of the terminal emulator.

Some in-terminal applications also have provisions that let them run
on terminals without function keys. For example, Midnight Commander
accepts ESC 1, …, ESC 0 (and thus also M-1, …, M-0) as equivalents of
F1..F10. Emacs could not adopt the same workaround though, because of
universal numeric argument.

(Also for historical reasons Midnight Commander opens its menu bar on
F9, not F10. F10 is Quit. This is because the MC descends in spirit
from Norton Commander whose keybindings were established way before
CUA.)

Windows applications (and applications on other GUI toolkits that use
mnemonics) open those menus when those letters are pressed with the
Alt modifier. Emacs mostly cannot do that because Alt+F is M-f is
forward-word. In Emacs-GTK you can choose a different modifier key for
Meta, but in terminal I’m not sure.
