* lisp/cus-start.el (standard): Copy custom :tag strings
from window-tool-bar-style's, which are more descriptive.

   When Emacs is compiled with GTK+ support, each tool bar item can
 consist of an image, or a text label, or both.  By default, Emacs

   You can also control the placement of the tool bar for the GTK+ tool
