Open Synaptic from the <gui>dash</gui> or the <gui>launcher</gui>. You will need to enter your password in the <gui>Authenticate</gui> window.

A shortcut to your new app will be added to the launcher. To disable this feature, uncheck <guiseq><gui>View</gui><gui>New Applications in Launcher</gui></guiseq>.

Click the <app>Ubuntu Software Center</app> icon in the <gui>launcher</gui>, or search for <input>Software Center</input> in the <gui>dash</gui>.

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>.

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

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.

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

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.

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

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.

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.

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.

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.

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.

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

You can right-click by holding down the left mouse button. This is useful if you find it difficult to move your fingers individually on one hand, or if your pointing device only has a single button.

Have a delay between a key being pressed and that letter appearing on the screen.

Turn on slow keys

Turn on sticky keys

<em>Sticky keys</em> allows you to type keyboard shortcuts one key at a time rather than having to hold down all of the keys at once. For example, the <keyseq><key>Alt</key><key>Tab</key></keyseq> shortcut switches between windows. Without sticky keys turned on, you would have to hold down both keys at the same time; with sticky keys turned on, you would press <key>Alt</key> and then <key>Tab</key> to do the same.

Synaptic is a powerful but complicated software management alternative to Ubuntu Software Center.

Use Synaptic for more advanced software management

<app>Synaptic Package Manager</app> is more powerful and can do some software management tasks which <app>Ubuntu Software Center</app> can't. Synaptic's interface is more complicated and doesn't support newer Software Center features like ratings and reviews and therefore isn't recommended for use by those new to Ubuntu.

Synaptic isn't installed by default, but you can <link href="apt:synaptic">install</link> it with Software Center.

Install software with Synaptic

Click <gui>Search</gui> to search for an application, or click <gui>Sections</gui> and look through the categories to find one.

Right-click the application that you want to install and select <gui>Mark for Installation</gui>.

If you are asked if you would like to mark additional changes, click <gui>Mark</gui>.

Click <gui>Apply</gui>, and then click <gui>Apply</gui> in the window that appears. The applications that you chose will be downloaded and installed.
