I'm trying to understand how I can add annotations that sit to the right of each line of a multiline equation. For example, in a proof, such annotations might provide justification for each step in the proof.
In pure LaTeX I could accomplish this like so: \begin{align*} h(x) &= \int_a^b{[f(x)+g(x)]dx} && \text{(Some annotation)}\\ &= \int_a^b{y(x)dx} && \text{(Another annotation)} \end{align*}' However, I'm not sure how to achieve the same effect in LyX. Abiel
