Insert

  1. To place information in-between other information, for example, placing text in-between other text is inserting text. If insert were not enabled when entering text in-between other text, the text would be overwritten as new text was being inserted; this mode is known as overtype mode. The insert mode is entered and exited using the Insert key.
  2. Term used to describe placing an object within another object. For example, placing a diskette into a computer could also be phrased as inserting a disk into the computer.
