The term togle is a versatile and useful technology term that refers to an object that toggles between different states with a single click. The term is primarily used in the computer world, although it can also be used in figurative contexts. It first appeared in the 18th century to refer to a type of fastener. Today, the word is used to describe a switch that toggles between up and down.

Toggling is a computer term that can refer to software and hardware switching. On a keyboard, for example, a key will toggle between the Caps Lock function and the Num Lock function. The concept works similarly in software. For example, an option menu will often have a toggling switch that can turn on or off the items in the menu.
