Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
help: don't crash in keyword search if an extension fails to provide docs Not all external extensions provide docs; if you use such an extension, you will experience a crash if you use "hg help --keyword <word>", and <word> happens to match the extension name.
