Visio process charting

[pepenacho]

Hello,

Does anyone know where I can find a good and thorough list of all the box
types used in Visio flow charting, organized by categories just as they are
in the software.

I'm wondering if that's on line somewhere, so I don't have to go into Visio
all the time. Those things are really useful when one puts a rough draft
together, in pencil form.

Thanks,
