It was encoded in 1998 in ISO 10646 Amendment 22 Keyboard Symbols, and then
published in 1999 in Unicode 3.0.
The first documents about "keyboard symbols" appear in 1997:
https://www.unicode.org/L2/L1997/Register-1997.html
https://www.unicode.org/L2/L1998/Register-1998.html
https://www.unicode.org/wg2/docs/n2100.htm

Many of these documents were on paper and don't have online versions.

In general, user interfaces do just fine with symbols as images, not
needing encoded characters, and not wanting to rely on variable font
support and glyph design.
