# Help `:help [search]` searches the Vim docs for the current command. However, search can be refined by prefixing the mode. * `:help R`: not so useful docs on replace mode * `:help ^R`: docs for `` * `:help i_^R`: insert contents of register in context of insert mode * `:help c_^R`: insert contents of register in context of command mode --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://timhwang21.gitbook.io/index/cli/vim/help.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
