Hold Home to glance at top, then release to return to previous scroll position.

I need to glance at member variables now and then, and it would be nice to be able to press and hold Home until I’m ready to return to typing. It would save me from additional keystrokes and would leave my cursor position in the same place onscreen before press and after release.

I could see the same functionality potentially being useful for End in a Pythonic if __name__ == '__main__' situation.
