Using the cases environment in LyX

Question

In LyX, how does one add multiple cases to a cases environment? When I insert the cases template, I get the opening bracket followed by two placeholder boxes, i.e.

{□□

I can put as much math in those two placeholders as I want, but I haven't been able to figure out how to add rows to this environment. Any ideas?

Answer 1

Try Shift+Enter or Control+Enter.

Answer 2

In Lyx, there is a "add row" button close to the "case environment" button. It is unavailable before being in the case environment, but it does the job then.

Answer 3

within the Google Document editor this problem also occurs and

\begin{cases}
1st\\
2nd\\
3rd\end{cases}

worked for me.
