I don't know if it helps, but essentially that is what I get with "darcs
send --edit", which I have enabled in my ~/.darcs/defaults.
After asking about patches, darcs starts up $VISUAL on a file that
contains the patch descriptions of outgoing patches.

I'd just have "k: back" then, rather than using a different letter.

I'm confused; are we still talking about "darcs send"?

Perhaps what's really desired is a --dry-run switch for all commands,
which prints a high-level description of the action that WOULD be taken,
but doesn't actually take it.
