Continuous zoom?

Hi, xdvi users and maintainers.

I was wondering if there be a more continuous screen shrinking and zooming
besides entire digit 1, 2, 3,...  In other words: to shrink or zoom the screen,
I hit `s' followed by an entire number, but this way I miss many intermediate
sizes...

Hope I was clear enough, sorry for my English...

Thanks for any help,

Rodolfo
