[texworks] Editing Hebrew with inline maths or English

[Moti Ben-Ari]

Thanks, Philip, Johannes.

First, I'm using pdflatex from MikTeX with babel. It is sufficient for the
informal document I'm writing for high-school math students.

After some experimentation I noticed that the TW editor works OK provided
that the math ends in an English letter:
$a_n = a_1 + (n-1)d$.
But if it ends with a number or punctuation mark then I get an editor
problem although they typeset correctly:
3$$  instead of $3$ and ${a_{51$ instead of $a_{51}$.

Following Philip's suggestion, I noticed that right-clicking brings up a
menu of over a dozen relevant unicode control characters. I tried a couple
and they seemed to solve the problem, but I don't understand the concepts
used. Can you direct me to a good tutorial??
