Problem with Alt + Middle Click Drag for Camera (Windows)

Okay, first of all, I'm completely new to Unity, and I know this is a very 'newbie' question. I realise that to move the scene camera I hold ALT, hold the middle mouse button and drag. However, that won't work for me.

My question is: is there any setting or similar to set this? Or am I doing it completely wrong?

The Alt+left click to rotate works, but the move camera will not work. Currently I am using either arrow buttons or the "pan" tool at the top, but neither are particularly efficient and a keyboard shortcut like the rotate one would be very helpful.

Thankyou very much in advance, Callum. :)

There is a hot key for the "pan" tool -- 'q'.

('q', 'w', 'e', 'r' are the top tools).

A 3-button mouse uses ALT + middle mouse button to move. When that stops working, you probably still can use the 2-button mouse function to drag. The short cut for that drag action is ALT + Control + left click.

For me you don’t need to press ALT if you are using middle click and so try that
