(third-person singular simple present backspaces, present participle backspacing, simple past and past participle backspaced)
backspace - Computer Definition
(1) To move the screen cursor one character to the left, deleting the character that was in that position. A backspace to the printer moves the print head one character to the left. In contrast, the DEL key deletes the character under the cursor. On Windows machines, there are backspace and DEL keys. On Mac laptops (not desktop computers), there is only a backspace key, which drives Windows users crazy when using a Mac laptop.
(2) To move to the previous block on a magnetic tape.
