What key do I have to hold down to move or zoom in 2.5D like we can in 3D? If this is supported it would be so helpful.
Zoom in with the ‘=’ key, zoom out with the ‘-’ key… 
Also, pressing “0” – the number, not the letter – will zoom the display to actual size.
And brand new to 1.5 is Ctrl+0, which zooms to a half-sized, antialiased display mode (also accessible through the Zoom palette).
Wow, great tip Matthew…Another thing I didn’t know… 
ok, while we’re on shortcuts, When I was in gyro mode with 1.23b, Rotate, I could press the CTRL + left click and it would snap in place; but now that is used for something else… I sure do miss it. Is there another shortcut for that?
Thanks guys!
