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"`

Um, currently Vimium C always clean info about recently-executed keys and commands, so there's no plan to add a command repeating last commands (which may lose efficacy in seconds).

抱歉设计上Vimium C不希望执行不受控制的未知代码，主要是图个安全。有什么功能需求的话可以去项目的github网页上提意见；需要自由写代码的可以试试greasemonkey

There's a feature of "global shortcuts", which allows to run commands anywhere using composed keys.
