# HG changeset patch
# User Bram Moolenaar <bram@zimbu.org>
# Date 1263910394 -3600
# Node ID 351bf13db8071317d7add1e55a50ae284ff53a4f
# Parent  85da0376313011aa957a9132df2686c9aba079d0
updated for version 7.2.334
Problem:    Postponing keys in Netbeans interface does not work properly.
Solution:   Store the key string instead of the number.  Avoid an infinite
	    loop. (Mostly by Xavier de Gaye)
