Selecting and Playing

To select a portion of a signal document to edit or play, simply press down on the mouse and drag in a view window. You can select in the vertical dimension by pressing the Alternate key as you drag the mouse. SE scrolls the screen if your selection extends beyond the current screenful.

If you press the Shift key and click on the mouse, the selection grows or shrinks to the point at which you click the mouse, depending on if you click outside or inside of the existing selection. Shift-Alternate-mouse-click causes the same selection behavior as Shift-mouse-click, except that the vertical dimension is also affected.

If you select a segment of length zero (by clicking without dragging), the selection flashes (provided that the window is the current view).

After you've made your selection, these selection-oriented commands become operational:

	Play		Command-, 
	Stop play		Command-.
	Zoom to selection	Command-=

When a signal document is playing, a vertical play cursor moves through the selected region in increments of 0.01 seconds.
