bug#32756: Customize UI Value Menu Label&Text Description is out of wack

[Van L]

Hello.

The label in the Value Menu should match exactly what is described in the 
documentation for the following:

1. Xref Prompt For Identifier
2. Dired Use Ls Dired

when using Customize UI.

An ideal user to verify the ability to achieve their goal whilst interacting 
with this aspect of the UI is to ask for feedback from a working writer, such 
as, a journalist. (Not me.)
