STDIN Question

[Hobbit HK]

I know that if I do:
$line=<STDIN>;

I'll read from STDIN until I'll press ENTER... My question is, how can
I change it? I mean, can I do that if I'll press, for example, "c"
it'll stop reading from STDIN? or, alternatively, can I do that it'll
stop reading after 2 chars?

perldoc -q key

I do know if those methods display each key pressed or leave it up to you
to echo them to the screen (with output buffering disabled and print
without newline, although, you may need a newline after accepting last
input).
