Please review the issue in its entirety: the name of the command, its
doc string, the text displayed in the respective menu item, the text
in the user manual.  Since you are talking about discoverability, we
must consider all of these, because the command's name is not the only
method of discovering it, not even the most important one.

Thanks.
