Hello, when Vomnibar is showing, `F2` can be used to switch focus between it and normal page content

Sorry there hasn't been a detailed list of available commands and their functionality and options - I maintain this project by myself and in my rest time, so I have no much time in writing docs, compared with adding features and fixing bugs.

Thanks for your suggestion. Maybe I'll add a new command to do so in months.

In the latest version, there's a new command of "addBookmark", and its usage is:
`map addBookmark path="/folder1/sub_folder2"`
