writing about keyboard

started to trickle into actually amassing and writing about Keyboard History ⌨.

Keyboard History ⌨

Added tens of photos in past month, and started to get a sense of keyboard evolution since 1960s. Keyboard history is a black whole. Well actually, not really. Math is, a hole.

Actually, working on keyboard makes me feel bad. It's petty. A petty thing. Writing comp lang tutorials is bad enough. A dismal petty fak complexity mostly of social causes due to programer idts faks. Dear god, when am i gonna be a real mathematian? God: neva!

IBM PC Keyboards (1981)

history of alt key


The history of the Alt key is a mystery to me still. I bet Marcin Wichary [ https://twitter.com/mwichary ] knew the answer.

recently i learned Meta key first appeared on the SAIL keyboard. (hope am correct) I'm not certain the date of SAIL, but must be between 1963 and 1974. SAIL keyboard also has a key labeled ALT. The SAIL became Knight Keyboard and became Space Cadget and other lisp machine keyboards. But in later ones, some of them has Alt Mode instead of Alt. Some also have Alt Lock. But some don't have any type of Alt key, e.g. PN 364000, PN 365407, and Xerox 1109.

it'd be nice if someone can tell us the history.

Also, the Alt on SAIL keyboard is the earliest Alt key i've seen.

The first other apart from lisp line that has Alt i found is: IBM PC model 5150 Keyboard, 1981

now i think the entire modifier business started on lisp machine keyboards, except Shift and Control. The meta alt or super hyper evolved into Mac's Cmd and Option. Alt Graph key may also be evolved from the Alt on lisp machines. The Window key of Microsoft may be inspired from Mac, and Microsoft invented the Menu key (but may be inspired or copy from some Xerox stuff.) Also, keep in mind that the way Alt works in Windows is not the typical modifier. When pressed by itself, it invokes menu, as a leader key of a key sequence. When pressed with other, it call commands, and can also insert chars similar to Alt Graph key. .

Touch-Typing in Japan

In Japan, the touch-typing rate even among college students is 15 percent. This rate is much lower than the 85 percent of American college students.
