<title>Middle-click</title>
<p>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>.</p>
<p>On touchpads that support multi-finger taps, you can tap with three
fingers at once to middle-click. You have to
<link xref="mouse-touchpad-click">enable tap clicking</link> in the
touchpad settings for this to work.</p>
<p>Many applications use middle-click for advanced click shortcuts.</p>
<list>
<item><p>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.</p>
<p>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.</p></item>
<item><p>On scrollbars and sliders, a regular click in the empty space moves
by a set amount (such as one page) in the direction you clicked. You can also
middle-click in the empty space to move to exactly the location you
clicked.</p></item>
<item><p>You can quickly open a new
window for an application with
middle-click. Simply
middle-click on the application's icon, either in
the <gui>Launcher</gui> on the left, or in
the <gui>Dash</gui>.</p></item>
<item><p>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>.</p></item>
<item><p>In the file manager, middle-click serves two roles. If you
middle-click a folder, it will open in a new tab. This mimics the
behavior of popular web browsers. If you middle-click a file, it
will open the file, just as if you had double-clicked.</p></item>
</list>
<p>Some specialized applications allow you to use the middle mouse
button for other functions. Search your application's help for
<em>middle-click</em> or <em>middle mouse button</em>.</p>
