Attempting to use a trackpad without a 3-button mouse. From this forum and others I see going to Edit | Preferences | Input | Check emulate 3 button mouse And choosing Emulate 3 Button Mo.. selecting either Alt or OS Key
Then, expected if I press G, then held the Command (Alt) or Globe/Fn key, I would see the graphic showing ability to snap to an axis. The graphic does not appear and holding the key has no effect.
