Laptop won't follow an editing step in a tutorial I am doing I am following a basic doughnut tutorial that I am doing on my laptop.

At some point, the guy in the video says while you have proportional editing mode on and have pressed the g key, 'scroll up or down' until a round circle appears that you use to model your shape with. However, When I try this, my laptop doesn't work.

I have emulated my middle mouse button and I am holding alt + left click while scrolling. Does anyone have any idea what is going on and what I might be doing wrong?
You do not have to hold down any mouse click to scroll or change the size of the proportional editing circle. Emulating middle mouse emulates a middle mouse CLICK (ie pressing the mouse wheel down like a button).

In proportional editing, begin the editing command (whatever it is, move, scale, rotate, etc.) then you are free to scroll to make the proportional editing circle larger or smaller by simply scrolling, usually 2 fingers up or down on the trackpad.

you can also use Page Up &amp; Down, but some laptops won't have that.
