### 3.4.1.2 Instant Zoom

Figure 3.14: Zoom-minus cursor that indicates the left mouse clicking is ready for zooming out.

While the canvas is still in zoom mode, instant zoom is enabled by default. Instant zoom allows zooming in at the point of left mouse clicking by a factor of 1/2; that is, the region centered at the point of left clicking will be magnified by a factor of 2. Also, the zoom focus time in the time display panel will be updated with the time where left clicking on the canvas is detected. In the process, the cursor remainsa zoom-plus cursor. Shift-click, on the other hand, will do the opposite. While the shift key is held down, the cursor will be changed to a zoom-minus cursor as in Figure 3.14, to indicate zooming out is the action associated with left clicking. The zoom factor is 2 in this case.
