	Oh, by the way, if you add the :GESTURE option to these two command
	definitions...

	    (define-command (e3-select :command-table e3-index)
		((article 'e3-article :GESTURE :SELECT))
	      (with-slots (selected-article selected-part) *application-frame*
			  (setf selected-article article)
			  (setf selected-part selected-article)
			  (setf (frame-command-table *application-frame*)
				(find-command-table 'e3-article))
			  (set-frame-layout *application-frame* 'e3-article-layout)))

	    (define-command (e3-select-part :command-table e3-article)
		((part 'e3-part :GESTURE :SELECT))
	      (with-slots (selected-part) *application-frame*
			  (setq selected-part part)))

	...then DEFINE-COMMAND will write these two translators for you, and
	you won't need to do it explicitly yourself.

	    (define-presentation-to-command-translator e3-select-icon
		(e3-article e3-select e3-index)
	      (object)
	      `(,object))

	    (define-presentation-to-command-translator e3-select-schema
		(e3-part e3-select-part e3-article)
	      (object)
	      `(,object))

    According to the documentation, :GESTURE NIL in this position implies
    "no translator at all" rather than its usual meaning of "a translator
    with no gesture (i.e., appearing only in the click-right menu)".  I
    assume that to get the latter behavior one must indeed write the two
    translators specifically.

It is a deficiency that :GESTURE NIL in this position implies "no
translator at all".  I will fix it, but I don't know when anyone will
actually see the fix.
