Bind key to a pdflink?

Is it possible, to bind a certain key (like "1") of the keyboard to a link
in my pdf-presentation? I have a system without mouse and i want to decide
by keyboard, which slide will be next.

It is very likely, that i have up to 9 links on one slide, wich need to be
adressed by the keys "1" to "9"

Thanks
