Double-click
A double-click is the act of pressing a computer mouse button twice quickly without moving the mouse. Double-clicking allows two different actions to be associated with the same mouse button. It was developed by Tim Mott of Xerox Palo Alto Research Center. Often, single-clicking selects (or highlights) an object (eg the space between two characters) while a double-click selects the next object up in the selection hierarchy (eg a word), or executes the function associated with that object (eg open a file folder). Following a link in a modern web browser is accomplished with only a single click, requiring the use of a second mouse button, "click and hold" delay, or modifier key to gain access to actions other than following the link. On touchscreens, the double-click is called "double-tap"; it's not used as much as double-click, but typically it functions as a zoom feature. ("triple-tap" sometimes used to zoom the whole screen.) On icons On most systems, double-clicking an icon in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triple-click
Triple-click is the action of clicking a computer mouse button three times quickly without moving the mouse. Along with clicking and double-clicking, triple-clicking allows three different actions to be associated with the same mouse button. Criticism of the double-click mechanism is even more valid for triple-clicks. However, few applications assign critical actions to a triple click. Examples of usage On text In most text processing programs and edit controls triple-clicking with the primary mouse button (the left button for right-handers) on the text selects the entire line. If the edit control is not multiline, the entire text is selected. Microsoft Word A triple-click within a paragraph in the text area selects the entire paragraph. A triple-click in the left margin (when the mouse pointer is an up-and-to-the-right arrow) selects the entire document.
