I keep hitting the middle mouse button by accident and getting stuff pasted into my buffer so how can I turn this off?
Here is an alternative binding, whereby the middle mouse button selects
(but does not cut) the expression under the mouse. Clicking middle on a
left or right paren will select to the matching one. Note that you can
(defun mouse-set-point-and-select (event) "Sets the point at the mouse location, then marks following form" (interactive "@e") (mouse-set-point event) (mark-sexp 1)) (define-key global-map [button2] 'mouse-set-point-and-select)
