hypertext markup language (HTML), tab-separated values (TSV), plain
text, or reStructuredText (reST) formats.

ps: "Open Browser" is a selenium defined keyword, so it's marked with blue color.We could search all the keyword by "F5".
We could also set every test case with a "Tags": Edit->Settings->Tags.So that we could run test cases with special tags.
