You could also just do volume envelpes (on the squeaks) and accomplish the exact same thing ... bypassing the whole "copying the squeaks to another track and flipping the phase" thing.
Unless you just like extra work.

If you flip the polarity on a track that is exactly the same, and add it in to the original, it is exactly the same as a volume knob. If the volmes of the two tracks are equal, they cancel and it is as if the volume was set at 0. If you raise one or the other, it's as if you are raising the level.
OTOH if you filter the squeek on the track that has the reverse phase to contain only the "squeeky" part, and add this it will canel out the squeeky stuff, but this is just like an EQ.
The real "trick" is to use a filter, and something like an upward expander so that the reversed track only comes in or is raised during the squeeks by an amount that isn't related to the original, then you have created a dynamic EQ.
I just used this technique yesterday to help get rid of a ring in a snare that was exactly in the range that I wanted to boost with an EQ. What a PIA ...
