Is there an OS trick to repeat mouse clicks?

I am on a Mac G5 OSX 10.3.9.
I am using reCycle to slice up break beats. I really prefer to choose 
my own slice points compared to the automated ones that reCycle 
selects.
I zoom right into the waveform and have to repeatedly click the mouse 
to make the screen scroll to the right until I make another slice 
point. I wish reCycle would keep stepping to the right of the screen 
cause I am concerned that clicking 100s of times per drum loop 
multiplied by 3-500 breakbeats will give me RSI.

Is there an OSX trick to make the mouse clicks repeat so I don't have 
to physically click repeatedly?
Heres hoping,
