Ah! I find that there is a flyspell-correct-word-before-point, already
set up with a key binding.

    flyspell-correct-word-before-point is an interactive compiled Lisp
    function in `flyspell.el'.

    It is bound to C-c $.

Perhaps this could be documented in the manual? Something like:

    When Flyspell mode highlights a word as misspelled, you can
    position point on it and type `C-c $' (or click on it with
    `Mouse-2') to display a menu of possible corrections and actions.

Also, this command pops up a graphical menu of options on my system.
This menu can be navigated fine from the keyboard which is good.
Nonetheless, it seems a bit incongruous to get a graphical menu in
response to a command from the keyboard. Might a minibuffer prompt or
completions list or an interface like the one used for ispell-buffer be
more appropriate? (I don't know, just asking.)
