What does double-click help us to select?

Double-clicking allows two different actions to be associated with the same mouse button. It was developed by Bill Atkinson of Apple Computer (now Apple Inc.) for their Lisa project. Often, single-clicking selects (or highlights) an object, while a double-click executes the function associated with that object.

What do you mean by clicking and double-clicking?

Typically, a single click initiates a user interface action and a double-click extends the action. For example, one click usually selects an item, and a double-click edits the selected item.

What are the uses of double-click?

A double click is most often employed to open the selected item whereas a single click is used to select items, follow hyperlinks, and activate buttons (such as submitting a form). On mice with two or more buttons, double clicking is usually done only with the primary (left) mouse button.

Is double-click accessible?

Double-clicking in a web context is extremely uncommon, so most users won't even think to do it. The uncommonness of double-clicking isn't strictly an accessibility issue.
