;; This module provides multi-click mouse support for GNU Emacs versions
;; 19.18 and later. I've tried to make it behave more like standard X
;; clients (eg. xterm) than the default Emacs 19 mouse selection handlers.
;; Basically:
;;
;; * Clicking mouse-1 starts (cancels) selection, dragging extends it.
;;
;; * Clicking or dragging mouse-3 extends the selection as well.
;;
;; * Double-clicking on word constituents selects words.
;; Double-clicking on symbol constituents selects symbols.
;; Double-clicking on quotes or parentheses selects sexps.
;; Double-clicking on whitespace selects whitespace.
;; Triple-clicking selects lines.

"Toggle Mouse Sel mode.
With prefix ARG, turn Mouse Sel mode on if and only if ARG is positive.
Returns the new status of Mouse Sel mode (non-nil means on).
When Mouse Sel mode is enabled, mouse selection is enhanced in various ways:
- Clicking mouse-1 starts (cancels) selection, dragging extends it.
- Clicking or dragging mouse-3 extends the selection as well.
- Double-clicking on word constituents selects words.
Double-clicking on symbol constituents selects symbols.
Double-clicking on quotes or parentheses selects sexps.
Double-clicking on whitespace selects whitespace.
Triple-clicking selects lines.
Quad-clicking selects paragraphs.
- Selecting sets the region & X primary selection, but does NOT affect
the `kill-ring', nor do the kill-ring functions change the X selection.
2000-08-08 18:32:38 +00:00
Because the mouse handlers set the primary selection directly,
mouse-sel sets the variables `interprogram-cut-function' and
`interprogram-paste-function' to nil.

- Clicking mouse-2 inserts the contents of the primary selection at
2001-08-21 18:19:55 +00:00
the mouse position (or point, if `mouse-yank-at-point' is non-nil).
1993-11-08 14:46:50 +00:00
- Pressing mouse-2 while selecting or extending copies selection
to the kill ring. Pressing mouse-1 or mouse-3 kills it.
- Double-clicking mouse-3 also kills selection.
- M-mouse-1, M-mouse-2 & M-mouse-3 work similarly to mouse-1, mouse-2
& mouse-3, but operate on the X secondary selection rather than the
primary selection and region."
