yep, I get this too - I'm going to have to change the font rendering
code for this, as atm it needs things to be changed where I don't have
control (in the drscheme init)

not yet, the priority is getting things working like the above, then get
things like the camera added. I've made a start on this - I've got
key-pressed and mouse-button etc working, I'll get this code released so
you can give it a try.

I'm not entirely sure what sort of thing you mean - in drscheme
read-char should work as normal, inside the scratchpad you could
probably build something using key-pressed:
http://www.pawfal.org/Software/fluxus/docs/0.13/en/scratchpad-input.html#key-pressed
but it might be a bit long winded this way.
