input: minor additions to default key bindings

This adds key bindings for some semi-popular features. It also tries to
cleanup some old bindings. For example w/e for panscan is now changed to
w/W. In all cases, the old bindings are still kept and work, though.

Part of an ongoing attempt to cleanup the default key bindings.
See #973 for some context.
