$W$ hat does $W$ refer to?

[Menasheh Peromsik]

I'd like to be able to run a magic word which has the $W$ parameter but doesn't require it.  If there's no way to do this now, maybe you could implement $w$ or something like that?

Yeah, today you have to just hit enter to use a blank parameter for $W$. Adding e.g. $W?$ makes sense to me.

Joining the conversation a bit late, but I guess it makes more sense to add here rather than on a new thread:

It would be nice to have a version of $I$ and $W$ that did NOT save the value on the history ...

Let me explain:  I have a few magic words which take sensitive parameters, like one I use to mount some network shares, and require the SMB user's password to complete.  I'd like that to not be saved to the history at all ...

Similar to the idiom for $W?$ and $I?$ proposed above, maybe $W*$ and $I*$ where the '*' is a nod to the default masking (*****) in password entry fields?   Or a completely new $P$ with P as in password?

Anyway, thanks A BUNCH for such a great utility that I've been happily using for many years now :)
