How do I change an equation number that was chosen automatically from
forcing a particular number or symbol?
That is, I want the analog of \tag in Latex
For example, I have an equation that is numbered "(5)" which is chosen
by default because it comes after "(4)". That's the correct normal
behavior of course. However, I want to break briefly out of the default
and number this one equation "(3')" because it is a variant of a
previous equation numbered "(3)".
Well, \tag will work. Stick the cursor in the equation. If it's
already being numbered, M-m n will remove the automatic number. Then
enter '\tag' followed by space, which will create a widget. In the
widget, type '\ensuremath' followed by a space to get a nested widget.
Type "3'" (or "3^\prime" if you're a purist) in the inner widget (no
parentheses). The display in the GUI is, ah, less than esthetically
pleasing, but it comes out right in the DVI. The inner widget is needed
to get you into math mode if you're going to use a superscript.
I'm not sure if there's a more LyXish way to do it.
