How do I replace text in a selection?

Question

I\'ve just started using Sublime Text 2, coming from emacs.

I have a region of text selected. Within that region, I\'d like to replace all text instances of \'0\' with \

Answer 1

1) Ctrl + F (or Cmd + F on a Mac);
2) Enter the string you want to find on the input at the bottom of the window.
3) Press "Find All";

All of the appearances are now selected. Do whatever you want.

Aside

There are a bunch of options at the left of the input that opens on Ctrl + F. There's one that says something like "Find in selected text". Select a bunch of text, check that option and repeat the same steps above starting from 2). Now, only matches belonging to that selection are selected.
