<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.</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>In the <gui>Activities</gui> overview, you can quickly open a new
window for an application with middle-click. Simply middle-click on the
application’s icon, either in the dash on the left, or in the applications
overview. The applications overview is displayed using the grid button in the
dash.</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.</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>
