You have a couple options:
1) HTML: Select the bracket(s) and Choose File -> Save Brackets As. (It will prompt you for a filename for each
2) PDF: A little harder on windows but if using a mac, just select the brackets and choose File -> Print. And then
either save as PDF or use the "Preview" button. On windows, there are free PDF print drivers. (Google Search for Free, PDF, Drivers)
We use CutePDF before and it's pretty good.
