Re: new wording for Undo

* > Does this mean “any” or “at least one”? *

I think my wording requires that use return to any previous step, which
I've made explicit below ... But I think we'll need to either put that out
for public comment or discuss with developers the implementation issues
involved in going back more than one step, and balance that against the
benefits.

When an action is one of a sequence of steps that need to be completed in
order to accomplish an activity, users can return to any previous step to
correct their data entry, without loss of data they entered, except when:

•       it would undermine privacy or security;
•       the user has confirmed an action;
•       doing so prevents an essential function of the content;
•       the data is no longer controlled by the site;
•       the user has not interacted with the site for 24 hours.


Cheers,
David MacDonald
