I've been trying to build my first useful mesh with GMSH with some success. I'm on a Mac with OS X 10.3.4 and GMSH 1.52.1. My question: where are the methods for interactively controlling the view (pan, zoom, etc.) documented? I seem to remember making that work a while back, but can't locate any documentation either in the help files or in the tutorials. Thanks for any help. Joe Koski
