Clicking a point with Alt-MMB will make it the point of interest: it becomes the central point which the view orbits around.
Holding Alt and then dragging with MMB in a certain direction will the view to an axis and make it orthographic.
Dragging with MMB and then holding Alt will perform an orbit while also snapping to the world axes, as well as the diagonals between them.

To change the viewing angle in discrete steps, use Numpad8 and Numpad2 to go up and down, or Numpad4 and Numpad6 for left and right. You can also press Numpad9 to switch to the opposite side of the view (rotates the camera 180° around the Z axis).

Shift-Numpad4, Shift-Numpad6

Rotate the viewport camera around its viewing direction in 15° discrete steps by default. See the rotation angle preference to configure.

To reset the roll, you can first align the view to the global X axis using Numpad3, then orbit to get back to the regular perspective view.

In most cases it’s sufficient to zoom the view to get a closer look at something. However, zooming only gets you up to the point of interest and no further. If you hit this point where zooming no longer works, you can instead Dolly by holding Shift-Ctrl and dragging up or down with MMB. This will move the point of interest (and the view along with it).
