Bob,
Once icons are placed on the control panel, the tooltip says
"Alt-click to
see menu, drag with meta key..."
On a Mac, with only one button, "alt" is the control or option keys.
So to see the popup menu I hold control and click-down on something.
"Meta" is the command (a.k.a. Apple) key, so I hold that down to move
things around.
Maybe control works the same on a Windows box?
Tried CTRL or ALT with left and right mouse buttons but nothing causes a
menu to pop up.
The right mouse button seems to be the "meta" key.
Can you view the sensor or turnout number once you place them on
the panel?
Uh, I don't know?
Sorry, not sure if you were responding above to the popup menu or the object
number question.
