Figure 4-8: Pinching
While "Zoom Select" is active (toolbar icon or softtool button is toggled on), spread-
ing and pinching is disabled. You can only select a rectangular area (using one fin-
ger) then.
●
In stimulus zoom mode, spreading and pinging is disabled by default. Only while
"Stim. Zoom Select" is active (toolbar icon or softtool button is toggled on), you can
use spreading and pinching to modify the sweep area and/or the vertical scaling.
Mouse vs. touch actions
Any user interface elements that react to actions by a mouse pointer also react to fin-
ger gestures on the screen, and vice versa. The following touch actions correspond to
