These are things that I tend to forget between times I use
3ds max
– To rotate the view, ALT+Middle Mouse. If it isn’t working as you expect, your camera pivot is probably too far
– Move tool: W, Rotate Tool: E, Scale Tool: R, if they aren’t working as you expect (manipulator looks wrong), PRESS X to fix it.
– To zoom in and out use []
Blender
– To select an object, RIGHT click
– Middle mouse rotates view, Ctrl+Middle Mouse zooms
– Z toggles wireframe
Maya
– CTRL+A shows the attribute editor
