Hi, I am writing a book using LyX, and I have a question regarding the formula numbering. An exclusive way to add and reference the formula numbers seems to be via "equation labels". This works, but appears rather irritating when one has to invent unique names for hundreds of equations. Is there no simpler way? I do not quite understand why these labels must be used, in the situation when LyX seems to keep track of every new equation all the time, and updates the equation numbers automatically. It would be much easier just to refer to the various equations by these formula numbers, without having to use additional labels.

What happens, then, when you add a new equation somewhere in the middle of the document?

Are there no plans to introduce such an improvement into LyX?

There has often been talk about automatic labelling, so that the equation would have its own "magic" label, so to speak, and you could reference it without needing to make up a label. But no one has found the need pressing enough to do it. Still, making up a label isn't that hard, and it can make it easier to remeber which equation you want to reference later. You can of course just use numbers if you wish. Richard
