There are many mice and some touchpads available that provides you a middle mouse button. In general mouse and touch pads doesn’t provides you the third click button i.e. middle click but now problem you can use third click by pressing both mouse buttons at the same time. This is more easy on laptops becuase there you have to put your finger on the place where both (left & right) click buttons meet each other (in center) and press both of them together, it seems difficult but its very easy. Or on a mouse with a a scroll wheel, you can usually press directly down on the scroll wheel to middle-click.
On touchpads that support multi-finger taps, you can tap with three fingers at once to middle-click. You have to enable tap clicking in the touchpad settings for this to work.

You can click, double-click, drag, and scroll using only your touchpad, without separate hardware buttons:

There are many apps that use middle-click for advanced click shortcuts.
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.
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.
You can quickly open a new window for an application with middle-click. Simply middle-click on the application’s icon, either in the launcher on the left, or in the dash.
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 Firefox web browser, though. In Firefox, 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 Enter.
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.
Some specialized applications allow you to use the middle mouse button for other functions. Search your application’s help for middle-click or middle mouse button.
