No, it inverts the 7th bit (or subtracts 64).

The Linux `ascii(7)` man page has a similar table, but with 2 columns. The first 32 control characters listed there have their "caret notation" character in the opposite column.

Is this why the symbol for Ctrl is also commonly the symbol for xor?!

I'm not sure. I think the caret is just a prefix to make it distinguishable from the normal letters.

It is the reason why Ctrl+i in a terminal is the same as Tab though. Likewise for Ctrl+m == Enter.
