[Vala] How to know if a key is being pressedf

[David Gomes <davidrafagomes gmail com>]

Is there a way of knowing if a key is being pressed without a whole
"override" function (event) for it?

Currently, I need to know if any of the Control Keys ("CONTROL_R", or
"CONTROL_L") and would like to do it in another function. Is there a way I
can do it?

Thanks
