if ever you don't feel cool enough when you properly unicodify an electrical unit like microamps as µA instead of uA, remember that you can also do ㎂ for even FANCIER unicode.

Or if you use Linux or similar you can add lower & upper case Greek to .Xcompose in home.
Then Compose g m gives μ
g l gives λ
G P gives Π
G O gives Ω
etc.

I have CapsLock as the Compose key.
I also added prime and double prime for feet/minutes inches/seconds: ′ and ″
Both typewriter ' " and regular quotes ‘ “ are wrong.

@raymaccarthy on Windows you can install WinCompose and get the same!

I did dual boot from 1998 to 2016 and in Jan 2017 erased Windows 7 from my daily laptop.
I also used the MS Unix for Window thing from 1998 that predated the Linux one and had a 3rd party X-windows server on NT 4.0.
