For example, after
sage: A,B,C = var('A'), var('B'), var('C')
sage: F = A*B+C; F
A*B + C
Is there some method you can call on F to extract A*B (or C)? This would be useful especially for displaying sage in LaTeX via sageTeX when a formula that is the sum of 4 terms (say) runs over the margin and has to be split up somehow. I would also be interested in a workaround in sageTeX that would allow you to flexibly insert a linebreak in a formula under the circumstances that the formula generated by Sage got too long for a line.
