Yes, this is safer.

Yeah, don't rely on the user doing anything that way you thought he
should do it.

Yes, ALSO. BUT you must not force the user to hit Return.
Look e.g. into preferences. Nearly every editor has also boolean gadgets
(just click) and string or numerical gadgets, too (type on the keyboard).
So it can easily happen that the user changes from gadget to gadget
simply by mouse clicking. This must not do harm to his inputs!

Like in street traffic, drive (and program) defensively, be aware
of ANY weird action the user might take.
