[Gvsig_english] Some basic questions

[Silvia Franceschi]

Hi Mario,
thanks for answering.

Would it be possible to keep the PAN option on pressing the mouse wheel
also if not in editing mode?

Now I got it! thanks!

Ok, that is not exactly what I was thinking about, this is useful but in my
case I would like to know the geometries only for some features where I am
working. An additional information on the INFO tool with the WKT of the
geometry would be useful.

Yes, but it seems that it doesn't work for me even if I selected all the
layers to snap on.

Yes, to be faster with GIS I usually use shortcuts instead of going with
the mouse and select each icon/tool. Examples are:
- activate in PAN mode
- activate SELECTION mode.
