Ignore quickly-repeated key presses of the same key.

Turn on bounce keys

Turn on <em>bounce keys</em> to ignore key presses that are rapidly repeated. For example, if you have hand tremors which cause you to press a key multiple times when you only want to press it once, you should turn on bounce keys.

Click the icon at the very right of the <gui>menu bar</gui> and select <gui>System Settings</gui>.

Open <gui>Universal Access</gui> and select the <gui>Typing</gui> tab.

Switch <gui>Bounce Keys</gui> on.

Quickly turn bounce keys on and off

You can turn bounce keys on and off by clicking the <link xref="a11y-icon">accessibility icon</link> on the top bar and selecting <gui>Bounce Keys</gui>.

Use the <gui>Acceptance delay</gui> slider to change how long bounce keys waits before it registers another key press after you pressed the key for the first time. Select <gui>Beep when a key is rejected</gui> if you want the computer to make a sound each time it ignores a key press because it happened too soon after the previous key press.

Use the <app>Orca</app> screen reader with a refreshable Braille display.

Read screen in Braille

GNOME provides the <app>Orca</app> screen reader to display the user interface on a refreshable Braille display. Refer to the <link href="help:orca">Orca Help</link> for more information.

Make windows and buttons on the screen more (or less) vivid, so they're easier to see.

Adjust the contrast

You can adjust the contrast of windows and buttons so that they're easier to see. This is not the same as <link xref="display-dimscreen">changing the brightness of the whole screen</link>; only parts of the <em>user interface</em> will change.

Open <gui>Universal Access</gui> and select the <gui>Seeing</gui> tab.

Under <gui>Display</gui> select the <gui>Contrast</gui> that best suits your needs. <gui>Low</gui> will make things less vivid, for example.

You can quickly change the contrast by clicking the <link xref="a11y-icon">accessibility icon</link> on the top bar and selecting <gui>High Contrast</gui>.

The Hover Click (Dwell Click) feature allows you to click by holding the mouse still.

Simulate clicking by hovering

You can click or drag simply by hovering your mouse pointer over a control or object on the screen. This is useful if you find it difficult to move the mouse and click at the same time. This feature is called Hover Click or Dwell Click.

When Hover Click is enabled, you can move your mouse pointer over a control, let go of the mouse, and then wait for a while before the button will be clicked for you.

Open <gui>Universal Access</gui> and select the <gui>Pointing and Clicking</gui> tab.

Switch <gui>Hover Click</gui> on.

The <gui>Hover Click</gui> window will open, and will stay above all of your other windows. You can use this to choose what sort of click should happen when you hover. For example, if you select <gui>Secondary Click</gui>, you will right-click when you hover. After you double-click, right-click, or drag, you will be automatically returned to clicking.

When you hover your mouse pointer over a button and don't move it, it will gradually change color. When it has fully changed color, the button will be clicked.

Adjust the <gui>Delay</gui> setting to change how long you have to hold the mouse pointer still before clicking.

You don't need to hold the mouse perfectly still when hovering to click. The pointer is allowed to move a little bit and will still click after a while. If it moves too much, however, the click will not happen.

Adjust the <gui>Motion threshold</gui> setting to change how much the pointer can move and still be considered to be hovering.

Use larger fonts to make text easier to read.

If you have difficulty reading the text on your screen, you can change the size of the font.

Under <gui>Display</gui> select the <gui>Text size</gui> that is big enough for you. It will adjust immediately.

In many apps, you can increase the text size at any time by pressing <keyseq><key>Ctrl</key><key>+</key></keyseq>. To reduce the text size, press <keyseq><key>Ctrl</key><key>-</key></keyseq>.

Pressing <key>Ctrl</key> can find the mouse pointer.

Quickly locate the pointer

If you have trouble seeing where the mouse pointer is on your screen, you can make it so that simply pressing the <key>Ctrl</key> key will locate your pointer. Once this is set up, pressing <key>Ctrl</key> will cause an animation to appear briefly at the location of your pointer.

Open <gui>Mouse and Touchpad</gui> and select the <gui>Mouse</gui> tab.

Select <gui>Show position of pointer when the Control key is pressed</gui>.

Your <key>Ctrl</key> keys will now locate the pointer when pressed.
