Show a message untill its get a input

I want a computer that shows a message untill its get a input
How?

a Redstone signal?`or some kinda rednet message?

both

i would first make an redstone signal example ( will edit, so you can choose which one. )
Wait a few mins… Check my pastebin in the post below

this is my little "tip" code.. everything is commented ( almost … just ask if you dont understand )

Pastebin: (most easy way)

it should not have any bugs.. (if it has then tell me so i can improve it )

Or key input?

. oh

of course.. will add it in…

added:

Well– i think that covers almost everything…

(added in the key feature, if you change the mode to 3 (its there by default))

Pastebin
(i just noticed that the id, isnt actually working xD (i did want it to display the "keys.enter" for example. but never mind))

everything should work, atleast..

:D/>
