Taking the snippet below as an example. If I try to add a Property below My

Bank using C-c C-x p I am offered completions for the Properties defined

under Web Site Passwords, not Bank Details. Is this a bug, or am I

misunderstanding the scope of the Columns directive?

The COLUMN property just defines the column view, not the properties

themselves.  When you set a property with `C-c C-x p', the prompt offers

completion over all the properties that are found in the current buffer.

Does that answer your question?

Thanks Bastien. Yes and no:) In my example if I type ACC in the mini

buffer Emacs returns No Match, whereas I assume it should offer

ACCOUNTNO as a completion.

This is not the current behavior.  

You have to actually use a property as a property (not as a column in
the :COLUMNS: property) so that the prompt offers it for completion.

But I agree it would be useful if Org were recognizing values in
:COLUMNS: as properties, even when they are not yet in use.
