This is platform specific. About 10 lines of code for a minimum 
implementation per OS, but if you don't wanna do it that way my 
library has a function for it with a prepackaged sample:

http://arsd-official.dpldocs.info/arsd.terminal.html#single-key

that's arsd-official:terminal on dub or you can grab the file 
from my github repo.

I guess you could view my source to see the impl but I don't feel 
like pulling it out right now.
