I like to switch between Source and Preview using the keyboard. One can switch from Preview to Source with Alt+V-E-S (View -> Editors -> Source), but to switch from Source to Preview, one has to press Alt+V-E-Down-Return, which is awkward. It would be nice if Alt+V-E-P worked.
You can now switch to the Preview using the Alt+V, E, P key sequence. Note that you can also switch between editor types using the Ctrl+Alt+PgUp/PgDown keyboard shortcuts in any editor window.
