Searching for "^" in the history

Searching for "^" in the history

[Vincent Lefevre]

Hi,

How can one search for the character "^" in the history (with
history-incremental-search-backward)? I've tried by escaping it
with \ but this doesn't work.

This doesn't work (quoted-insert is for special characters in the
terminal sense, ^ is a special character for the history search).

The only way is to not put it as the first character in the search
string -- i.e. to search for the character prior to the "^" as well as
the "^" itself.  Yeah, that means that there is no way to search for
just a "^" in zsh's current code.  In the future it might be nice to
upgrade the incremental search to a regex-understanding search like vim
uses (it treats invalid regex elements as literal strings, so you can
eaily search for something like "[" or "$" without having to backslash
it).

The problem is that I don't know this character.

Or could zsh be modified so that searching for ^^ (at the beginning of
the search string) is like searching for the ^ character? I doubt that
searching for the ^ character as the first character of a command (as
^^ currently does) is really useful.
