The always interesting Pasa Bon! piques our curiosity regarding the punctuation mark known by the titular name or rather the index or the printer’s fist—scribes employing this symbol (☞, see also) to highlight and annotate corrections or notes.
Incorporated into standard typography, the sign’s modern sense is to direct readers to a cross-reference, point the way in advertising and was shorthand (reference the above stenography) of essayist H L Mencken to express the aphorism “When you point a finger at someone, realise that there are three pointing back at you,” bookending his telegrams with this reminder. Of course, the index also has a walk on role, a cameo according to what we’re mousing over. Much more to explore at the links above.
