Changing Views

[imagine]

What I miss is a key to "normal 3d view" to come back from an axis view, I mean, when in default view I press Y to view from Y axis (top view), what key I have to press to come back to default view? I use R key (reset view) but this completely resets the view, including zoom applied, what I really want is a key to come back to the view I had just before switching view (i.e. pressing Y key)
