When selecting, copying and pasting from various documents (for example from
an HTML web page) you must go in via Paste Special if you wish to select a
type other than HTML. I'm presuming it defauts to the same type as from
which you perform the copy.

It would be nice to be able to select "set as default" if I always want to
paste unformatted text.

I have not been able to find if that is possible.
