The important difference is that you could do

and select subkeys one and two. But either

will not select the primary as well as two subkeys. You can, however,
use "key 0" to return to extending the expiration of just the primary.

TIL, "*" will select all subkeys. I did not know that.



I use the GNU Privacy Guard (GnuPG) in combination with Enigmail.
You can send me encrypted mail if you want some privacy.
