The space bar, spacebar, or space key, is a key on an alphanumeric keyboard in the form of a horizontal bar in the lowermost row, significantly wider than other keys. Its main purpose is to conveniently enter a space, e.g., between words during typing. It is large enough so that a thumb from either hand can use it. The space bar key is almost always found on the bottom row of standard QWERTY or Dvorak keyboard layouts. Although it varies by Operating System, the space bar usually lies between the Alt (Windows) or Command (Mac) keys and below keys: c, v, b, n, m.
Depending on the operating system, the space bar used with a modifier key such as the control key may have functions such as resizing or closing the current window, half-spacing, or even backspacing. On web browsers, the space bar usually allows the user to scroll down or to scroll up when the space bar is used with the shift key.
In many programs for playback of linear media, the space bar is used for pausing and resuming playback, or for manually advancing through text.
Famous quotes containing the words space and/or bar:
“Thus all our dignity lies in thought. Through it we must raise ourselves, and not through space or time, which we cannot fill. Let us endeavor, then, to think well: this is the mainspring of morality.”
—Blaise Pascal (1623–1662)
“O City city, I can sometimes hear
Beside a public bar in Lower Thames Street,
The pleasant whining of a mandolin
And a clatter and a chatter from within
Where fishmen lounge at noon.”
—T.S. (Thomas Stearns)
