I have a standard keyboard and I type greek letters easily. ALTGR+a, and so on.

If somebody is not able to configure their keyboard to do this they are not probably writing LaTeX, either.

If memory serves me correctly, there was no way to type those symbols on an Acorn A5000 which is where I did the bulk of my LaTeXing back in the day (1992-95).

(Admittedly, this anecdata is even more useless than usual.)
