|
678 Default behavior is as follows:
|
|
|
679
|
|
|
680 If you click-and-drag, the selection will be set to the region between the
|
|
|
681 point of the initial click and the point at which you release the button.
|
|
|
682 These positions need not be ordered.
|
|
|
683
|
|
|
684 If you click-and-release without moving the mouse, then the point is moved
|
|
|
685 and the selection is disowned (there will be no selection owner). The mark
|
|
|
686 will be set to the previous position of point.
|
|
|
687
|
|
|
688 If you double-click, the selection will extend by symbols instead of by
|
|
|
689 characters. If you triple-click, the selection will extend by lines.
|
|
|
690
|
|
|
691 If you drag the mouse off the top or bottom of the window, you can select
|
|
|
692 pieces of text which are larger than the visible part of the buffer; the
|
|
|
693 buffer will scroll as necessary.
|
|
|
694
|
|
|
695 The selected text becomes the current X Selection. The point will be left
|
|
|
696 at the position at which you released the button, and the mark will be left
|
|
|
697 at the initial click position."
