I already use middle mouse to paste/yank. However flyspell seems to hijack this, making it impossible to paste in the vicinity of a correctable word.

With the help of this question I have discovered that I can add the correct-word functionality to the more sane right-mouse button with

(eval-after-load "flyspell"
     (define-key flyspell-mouse-map [down-mouse-3] #'flyspell-correct-word)
     (define-key flyspell-mouse-map [mouse-3] #'undefined)))

however this doesn't change the middle mouse button behaviour.

How do I clear flyspell's default binding of the middle mouse so I can always use middle mouse to paste? It would also be appreciated if the relevant lisp could be explained. Although I managed to copy and paste the above to good effect, it's inner workings are a mystery to me.

    Just a guess, by maybe bind [mouse-2] and [down-mouse-2] to nil in flyspell-mouse-map?

  • @Dan That's the answer. mouse-2 is middle mouse button. To confirm, hit C-h c <middle mouse button click>

You can extend your current code to bind [mouse-2] and [down-mouse-2] to nil in flyspell-mouse-map:

(eval-after-load "flyspell"
     (define-key flyspell-mouse-map [down-mouse-3] #'flyspell-correct-word)
     (define-key flyspell-mouse-map [mouse-3] #'undefined)
     (define-key flyspell-mouse-map [down-mouse-2] nil)
     (define-key flyspell-mouse-map [mouse-2] nil)))

Thanks to @nanny for testing it out.

What the code is doing is:

  • Telling emacs that you want to make some modifications only after it loads flyspell (that's the eval-after-load part).
  • The progn tells emacs that you're going to tell it to do a number of things.
  • Each of the define-key lines tells emacs that you're going to change something in the flyspell-mouse-map.
  • Setting a binding to nil tells emacs that it should do nothing in that map.

In other words: unbinding it in flyspell-mouse-map means that flyspell won't override your existing middle-mouse-as-yank setup.
