Input: Question: How did 7 come to be an abbreviation for 'and' in Old English? is a beautiful question about the Tiroian "et", which is now the "" character 1. My question is what impact did the association of this 7-like-glyph have on the eventual placement of keyboards placing the & on Shift+7 combination? The Wikipedia article on the QUERTY keyboard shows that the ampersand was a separate key in the bottom left of the keyboard in the original patent application drawings. The patent was filed in 1878. The Das Keyboard blog shows a Full Duplex keyboard (with separate keys for upper and lower case letters) from 1897 with no ampersand key at all. I have not yet been able to find a reference to the first keyboard to place the ampersand and 7 together. The Wiki article on the ampersand only mentions that it is usually keyed via Shift+7, but occasionally on 6 or 8 instead. Dvorak layouts appear to share similar associations between 7 and &. So is it a coincidence? Or is there some association? 1 This looks really different in the EL&U site fontface. See the linked question or the Wikipedia article for more faithful renderings. 
Answer: Although the 7 was the ampersand on IBM's standard keyboard layout, that is hardly universal. The first nine printable characters in ASCII are ! " # $ % & ' ( ), which should give a good clue as to what the top row of a teletype keyboard looked like. On many early teletypes and terminals (and also, BTW, on the Apple ][), the shift key toggled bit 4 of the character being produced, thus it would turn a 1 (011 0001) into ! (010 0001), and , (010 1100) into < (011 1100). Since the digits 1-9 received consecutive code, so did the characters produced by combining them with the shift key. Shift-7 on those keyboards was apostrophe; the ampersand was shift-6. Other typewriter keyboards also varied considerably in where they put the ampersand. Its association with the number 7 is nowhere near as consistent as the association between 1 and !, 3 and #, 4 and $, or 5 and % which existed in both older computer keyboards and today's US arrangement.
