Scrolling speed
By default, the magnifier scrolls across the screen automatically. The
Scrolling speed
setting controls the
speed of this automatic scrolling (see section 6.3.7) as well as the speed at which you can scroll manually
with the navigation keys. You can select a value from 1 (slowest) through 6 (fastest).
6.3.7
Auto-scroll delay
As described in section 6.3.6, the magnifier scrolls across the screen automatically. However ZOOMS
waits for a short period of time after the last change on the screen before the automatic scrolling begins.
Use the
Auto-scroll delay
setting to control how long ZOOMS should wait before beginning the
automatic scrolling. You can select a value from 0.25 second to 4 seconds. If you don’t want the magnifier
to scroll automatically, select
No
. You can scroll manually with the navigation keys.
The speed at which the magnifier scrolls depends on the
Scrolling speed
setting (see section 6.3.6).
