For Users with Disabilities
Motor Impairments and Mouseless Operation
If you can operate a mouse, but have trouble clicking, the
KMouseTool application may help. Run it from
->
->
.
The
KDE Control Center offers several keyboard features collectively called XAccess.
They include:
-
Sticky Keys
-
This feature permits operation of meta keys, such as
Alt
,
Ctrl
, and
Shift
without having to hold the keys down. It is useful
when you can only use one finger or one hand to operate the keyboard.
With Sticky Keys on, press and release a
Alt
,
Ctrl
, or
Shift
key, then
press another key. The result is as if you pressed both keys at once.
Press the
Alt
,
Ctrl
, or
Shift
key again to turn off the sticky key.
Activate this feature in
->
->
->
.
-
Slow Keys
-
This feature is useful if you have hand tremors or difficulty
accurately pressing keys. It prevents
inadvertent key presses by requiring that a key be held down for a minimum
time before it is accepted. Activate this feature in
->
->
->
.
-
Bounce Keys
-
This feature is also useful if you have hand tremors. It prevents
inadvertent repeated key presses by preventing another keystroke for
a certain amount of time. Activate this feature in
->
->
->
.
Mouse Emulation permits you to move and click the mouse using the keyboard.
Press
Alt
-
F12
to activate it. Use the arrow keys
to move the mouse pointer to the desired location, and press
spacebar
to "click" the mouse. Unfortunately, you cannot use Mouse Emulation to perform
right mouse button clicks or dragging.
This feature permits you to emulate the mouse using the numeric keypad
of your keyboard. To activate it, go to
->
->
->
->
.
Check the
Move pointer with keyboard (using the num pad)
box. When you do this, the other settings will become enabled, and you can customize the keyboard pointer behavior further, if required.
The various keys on the number pad move in the direction you would expect. Note that you can move diagonally as well as up, down, left and right. The
5
key emulates a click to a pointer button, typically left mouse button. You change which button is emulated by using the
/
key (which makes it left mouse button),
*
key (which makes it middle mouse button) and
-
(which makes it right mouse button).
Using the
+
emulates a doubleclick to the selected pointer button. You can use the
0
key to emulate holding down the selected pointer button (for easy dragging),
and then use the
.
to emulate releasing the selected pointer button.
Use the
Menu
key to pop up the context
menu. On most keyboards, the
Menu
key is on the righthand
side of the keyboard between the
Windows�
and
Ctrl
keys. It has a menu icon on it.
You can move the sizing bar between the outline panel and the
slide panel, and between the slide panel and the notes panel
by pressing
F8
. A sizing icon appears
overtop the sizing bar. Pressing
F8
again moves from one
sizing bar to the next. After the last sizing bar, pressing
F8
hides the sizing icon. Use the arrow keys to move the bar up or down, or left or right.
Press
Esc
when finished sizing.
Normally, one can use the
Tab
and
Shift
+
Tab
to move focus from one widget to the next in any application. However, when focus is
in the slide panel of KPresenter, pressing
Tab
does not move the focus.
You can set focus to any widget that can receive focus by
pressing
Alt
+
F8
. A small lettered box appears
overtop each widget on the screen that can receive focus.
Press the letter to move focus to the corresponding widget. Press
Alt
+
F8
again or
Esc
to abandon moving the focus.
