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.
@foone
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.
