I admit to not having used Global Variables since last summer and things may have changed in the interim. However, Global Variables (historically) have always come into a Part or Assembly file in CAPITOL LETTERS which makes "forcing them" to the "top" of the Equation Editor list nearly impossible. Lower ASCII value identities show up at the "top" of an Equation Editor value list -- which is why I identify Equation Editor values starting with "a0," "a1," "a2," etc.
