Hmm... there's no such thing as a protected enspace.

I think that you misunderstood \enskip and \enspace. They both have a
length of 0.5em, but \enskip always inserts horizontal space, whereas
\enspace inserts horizontal space when in horizontal mode but vertical
space when in vertical mode. Try the attached latex snippet for a
surprise...
I think that for latex experts it would be confusing having a "Enspace"
menu that really inserts \enskip. What is the problem in simply renaming
"Enspace (0.5em)" to "Enskip (0.5em)" and getting rid of the "Enspace"
in the context menu?
