Backspace
The backspace key ( German backspace , backspace or return Delete key , no common abbreviation) is a key of the PC keyboard that the on operation cursor one position shifts to the left and standing there signs removed. This corresponds to the function of the correction key on typewriters with a correction function. It deletes in the opposite direction of the delete key . On keyboards, the key is often labeled with ←or ⌫.
Most Web browsers interpret the backspace key as "Back" - that is, in the course previously requested page is called.
The control character for the backspace (BS) has the value 8 in ASCII and corresponds to ^ H ( + ) in many terminals . With EBCDIC , BS has the value 16 hex . If an ASCII terminal does not have the function to move the cursor to the left, ^ H is output instead . StrgH
An extension of the backspace is (especially under Unix / Linux ) ^ W ( Strg+ W) or the combination Strg+ Backspace(analogous to the combination Strg+ Entf), with which the last word can be deleted, i.e. that is, all characters up to the last previous whitespace are removed. You can also use ^ U ( Strg+ U) to delete all previous characters in the current line. Some text editors such as vim or emacs also offer this option.
Unicode contains the character ␈ (U + 2408) as a symbol for the control character.
Metaphorical meaning
In allusion to the representation of the associated control character using ^ H , a word is sometimes started in a sentence in Internet forums and then "deleted" with a written "^ H" to represent a kind of intentional Freudian slip of the tongue:
Weil ich feig^H^H^H^Hvorsichtig bin, nur ein harmloses Beispiel
It shows what was actually meant, but was then "deleted".
