[Usability] Showing vs. Displaying

[Gregory Merchan <merchan phys lsu edu>]

I was grepping through sources to see how applications remotes are working
with multi-head (see bug #114219), and I found many translatable strings
using "display" as a verb. Is this correct? Shouldn't the verb be "show"?
"Show" is 3 letters and 1 syllable shorter. It is also more familiar having
a polysemy count of 13 vs. 3 for "display". Is there a meaning disctinction
dictating the use of either?

I see the GDP style guide defines "display" as a user action.
http://developer.gnome.org/documents/style-guide/gnome-glossary-user-actions.html
It does not define "show", but it uses it.

Befuddled,
Greg
