We can get input from console by input or ask, which means to press some keys on keyboard and terminate the input by pressing the key "Enter".
I'd like to know if there is a way to get a key input, that is to say, just press a key on keyboard and then something happens, like this:
if read-key = #"a" [do something...] ;;if the key "a" on keyboard is pressed, something is done immediately--not by pressing the key "Enter" after pressing "a".
If no such any-function! like read-way in red/rebol, how to achieve it?
On Rebol2 this should work:
>> console-port: open/binary [scheme: 'console]
>> pick console-port 1 ; hit space
== 32
>> to char! pick console-port 1 ;hit x
== #"x"
