How do I use regex curly braces in SublimeText2

Question

SublimeText's regex parser doesn't seem to work like others.

If I write (.*{50, 51})+, or (.*{50,})+, or (.*{50})+, it doesn't grab sets of 50 characters. I think it tries to match the { as a literal.

How can I use the min/max occurrance syntax in Sublime?

Answer 1

Ah it was the * that got me. How silly of me. It works without the double repetition specifier.
