If it turns out that mouse clicks can't be prefix keys, then the doc

Yeah, I'm having trouble going through it. Is there a way to make it
supported, though? For example, what about catching the error around
read_char_x_menu_prompt (keyboard.c:L2683) and not exiting if an error
was thrown? I'm not sure how to go about this in C.

Do you mean those mentioned in "(emacs) Menu Mouse Clicks"? Does
clicking in those menus count as key sequences?
