CommuteEverything[expr]

Aliases: CE

Description: It changes NonCommutativeMultiply to Times in $expr$.

Arguments: $expr$ is an algebraic expression.

Comments / Limitations: Very useful for getting ideas in the middle of a complicated calcuation. If $expr$ has you baffled, type $exprcom=CE[expr]$. $exprcom$ is commutative and therefore is easy to analyze. Now $expr$ is uneffected, so you can get back to working on it armed with new ideas.
