Answer:
There are several options for this.1. You can activate the "Move view, Zoom [Shift], Rotate [Ctrl] or Activate [Alt]" command. See Image 01.
When the command is activated, you can hold down the left mouse button and click [Shift], [Ctrl], or [Alt] to change the view.
2. To rotate, hold down the [Ctrl] key and the middle mouse button (the mouse wheel). You change the view by moving the mouse.
3. As an alternative to the [Ctrl] key in step 2, you can also hold down the right + middle mouse buttons and move the cursor.
