Hiding Using Filling - <F> key

Typing <H><F> is a shortcut version of the surface hiding sequence <G><F> <H><G>.

Because it uses the marking mechanism to select the faces, any faces that happen to be already marked will also be hidden.

Swapping Hidden Faces - <S> key

Type <H><S> to swap the visible and hidden faces.

Showing Hidden Faces - <U> key

Type <H><U> to unhide all hidden faces.

Zoom In On Visible Faces - <Home> key

You can zoom in on the remaining visible faces by aiming the mouse pointer at some background then type the <Home> key. If you aim the pointer at a piece of mesh, then <Home> will focus in on that area.
