I am typesetting an entire math lecture script, where readability often requires me to indent just a line or two for a certain amount, which is ALWAYS different. I would like to have some way of controlling the indent of the next line by an & like in tables, or any other control character. I do not want to use tables though, I want it to look like normal text. It obviously has to work inside and outside of math environments, since they appear in text quite often for this project.
It should look something like this:
This is the first line. One more line. And another.
With the control charcters being in front of "is" and "line".
Is there an easy-to-use solution? I don't care if it is complicated to configure once, as long as the use is simple every time.
