4.6.4. Input Filtering: SlowKeys
To access the control in the
SlowKeys
section, you must have checked the
FilterKeys
box and the
Ignore
quick input and slow down repeat rate
button in the
FilterKeys
section. To prevent accidental key presses
from activating a key, you can set the minimum time that a key must be depressed before it registers. This is
done using the
Keys must be held down
for
control. The default delay time is one second. You can change
the delays in increments of 0.1 seconds (100 milliseconds).
4.6.5. Input Filtering: BounceKeys
To access the control in the
BounceKeys
section, you must have checked the
FilterKeys
box and the
Ignore repeated input
button in the
FilterKeys
section. By setting the
Ignore inputs faster than
control,
you can prevent the system from responding to accidental keyboard presses that follow one another very
quickly.
4.7. Input Configuration: Scanning Dialog
If you are unable to easily access the onscreen buttons, you might want to use scanning access. Most of the
configurations that come with your Palmtop device can be accessed in scanning mode. Scanning is enabled
by checking the
Scanning
box in the
Input
section of the
General
dialog. To bring up the
Scanning
dialog,
select the
Configure
button to the right of the
Scanning
check box.

4.7.1. Scanning Dialog: Method Section
Palmtop supports single switch (“automatic”) and dual switch (“manual”) scanning. If the
Single Switch (Std)
option is selected in the
Method
drop-down menu, the software will operate in autoscanning mode - it will
automatically step through the rows at a constant rate until you activate your switch to specify the desired
column. It will then automatically step through the columns of that row until you activate the switch again to
specify the desired character or word. The autoscanning rate can be made faster or slower by changing the
scanning delays. See section 4.7.2 for details.
You can activate an alternative single switch scanning mode by selecting
Single Switch (Inv)
in the
Method
drop-down menu. In this mode, scanning will not start until you activate the switch and keep it held down.
The system will step through rows until you release the switch to select the desired row. You must then
activate and hold the switch again to begin scanning through the elements in that row. To select an individual
character or word, release the switch when that desired element is highlighted. Inverse scanning gives you
control over exactly when scanning starts. This can be useful since it allows you to visually locate the desired
character or word before starting the scanning process.
