Thank you for this tip!
>From the documentation of the "draw" command ("hoverText": text that
will appear after issuing set drawHover TRUE (Jmol 11.1)) I expected the
text to appear only if the mouse rests over the draw object. Because
that wouldn't help me much, I didn't even tested it.
But the text appears (fortunately) directly after the definition and I
couldn't observe any difference after changing "set drawHover".
So it looks as if I could use it directly to label planes. And to switch
the label off, just redefine the plane without the text.
When I tried the example 'draw text1 {3 4 5} "some text label"
translucent 1' I got the following Java error with Jmol 11.2.0 (SuSE
Linux 9.3, Java 1.4.2_13, Firefox 1.5.0.10) and the applet doesn't
refresh the window any more:

But this error seems to occur only if this is the first draw command
issued. If I start with 'draw text1 {3 4 5} "some text label"' first and
then add 'translucent 1' in a second command, no Java error occurs.
