What's the history of using ^ to indicate a control character? Wikipedia (https://en.wikipedia.org/wiki/Caret_notation https://en.wikipedia.org/wiki/Caret_notation) didn't provide any history.
- simonh 7y agoI suspect it may be down to the use of the Caret key on typewriters and teleprinters as a modifier on other characters. Often the caret was a ‘dead key’ that did not advance the carriage, so you could then type another character in the same location, which would be accented by the caret mark. If you wanted a caret by itself you had to then press the space bar. The control key is also used to modify the meaning of another key, and does not advance the cursor.
