For bash keywords, don't look in the man page, try "help <word>". The Bash man page does not contain a complete description of Bash, only a brief summary. "man <builtin>" provides a generic builtins page usually, since the builtins can vary between shells so one man page can't cover all of the different shell behaviors. However, bash has a "help" command which will give you the bash-specific description of a given builtin. Other than that, I usually find the HTML Bash documentation easier to read and navigate than the info, so I just use that instead. And yes, the sudoers man page is pure evil.
