To create your own keyboard shortcut:

Custom shortcuts

Open <gui>Keyboard</gui> and select the <gui>Shortcuts</gui> tab.

The command name that you type should be a valid system command. You can check that the command works by opening a Terminal and typing it in there. The command that opens an application may not have exactly the same name as the application itself.

If you want to change the command that is associated with a custom keyboard shortcut, double-click the <em>name</em> of the shortcut. The <gui>Custom Shortcut</gui> window will appear, and you can edit the command.

Turn off repeated key presses

Set keyboard shortcuts

By default, when you hold down a key on your keyboard, the letter or symbol will be repeated until you release the key. If you have difficulty picking your finger back up quickly enough, you can disable this feature, or change how long it takes before key presses start repeating.

Define or change keyboard shortcuts in <gui>Keyboard</gui> settings.

Turn off <gui>Key presses repeat when key is held down</gui> to disable repeated keys entirely.

To change the key or keys to be pressed for a keyboard shortcut:

Alternatively, adjust the <gui>Delay</gui> slider to control how long you have to hold a key down to begin repeating it, and adjust the <gui>Speed</gui> slider to control how quickly key presses repeat.

Make the keyboard not repeat letters when you hold down a key, or change the delay and speed of repeat keys.

If you have a mouse with a cable, check that it is firmly plugged in to your computer.

If it is a USB mouse (with a rectangular connector), try plugging it in to a different USB port. If it is a PS/2 mouse (with a small, round connector with six pins), make sure that it is plugged in to the green mouse port rather than the purple keyboard port. You may need to restart the computer if it was not plugged in.

Most web browsers allow you to open links in tabs quickly with the middle mouse button. Just click any link with your middle mouse button, and it will open in a new tab. Be careful clicking the link in the <app>Firefox</app> web browser, though. In <app>Firefox</app>, if you middle-click anywhere except on a link, it will try to load your selected text as a URL, as if you used middle-click to paste it to the location bar and pressed <key>Enter</key>.

One common shortcut is to paste selected text. (This is sometimes called primary selection paste.) Select the text you want to paste, then go to where you want to paste it and middle-click. The selected text is pasted at the mouse position.

Pasting text with your middle mouse button is completely separate from the normal clipboard. Selecting text does not copy it to your clipboard. This quick method of pasting only works with the middle mouse button.

Many applications use middle-click for advanced click shortcuts.

You can swap the behavior of the left and right buttons on your mouse or touchpad to make it more comfortable for left-handed use.

Many mice and some touchpads have a middle mouse button. On a mouse with a scroll wheel, you can usually press directly down on the scroll wheel to middle-click. If you don't have a middle mouse button, you can press the left and right mouse buttons at the same time to middle-click. If you find you are unable to middle-click this way you can try following <link href="https://wiki.ubuntu.com/X/Quirks#A2-button_Mice"> these instructions</link>.
