Welcome to the forums!
No question is too simple to ask at BlenderNewbies!
I think what you're referring to is the ability to rotate the 3d view. You can do this by pressing and dragging with the middle mouse button. Your roller (or mousewheel) in the middle should also be a button that you can press. If not, then you'll probably need to get a newer mouse. Is your mouse old or was it purchased within the past few years?
For the "little red 3d symbol", I think you're referring to what's called the "Mini Axis" that's located in the lower left corner of the 3d view? It may have gotten disabled in the Preferences. To check, pull down the horizontal splitter at the top to reveal the Preferences window. Select the "View & Controls" tab button and locate the "Mini Axis" option found right above the Themes tab button. Make sure it's pushed in and you should see the mini axis in the lower left corner of the 3d view.
Hope that helps!


I see the headers on top of my form page, but I don't see the 3D notation in the header that is hovering over my one dimensional cube. Possibly when I change the mouse to a three button mouse, I will get the 3D cube. When I bring the monkey into my form, the monkey is 3D. But I can't get the one dimensional cube monkey off my back. (small bit of humor)
I purchased a new mouse, Arc mouse from Microsoft, and taking advice on changing the 3D settings worked for me. Now I can rotate the cube in 3D, small start on a long road ahead, but smiling now. It is lots of fun having such a good backup as this forum.
