# Registers ## Special registers `@` followed by a register symbol represents a register. In addition to the standard numbered registers `@[0-9]`, there are several special registers. * `:`: command register * `/`: search register * `%`: filepath register * `"`: last yanked value register * `+`: system clipboard register * `=`: expression register `:reg` for a complete list. ## Modify register contents with `REGISTER` Note that since macros are just command sequences stored as a string in a register, you can edit macros this way as well. ``` :let @q='q' # ...and then modify ``` ## Reuse contents of search register Useful for when you search for something unwieldy to type and need to reuse it later (for a replace for example). ``` /some-long-and-complicated-search-string # search something arcane :%s///replacement-string # reuse without retyping ``` ## Yank to system clipboard ``` "+y ``` ## Set system clipboard contents to current filepath ``` :let @+ = expand("%") ``` ## Run function on search results Useful for transformations. The following will dashcase all capture group matches using [abolish.vim](https://github.com/tpope/vim-abolish). ``` g/\attribute :(\w\+\)/\=g:Abolish.dashcase(submatch(0)) ``` --- # 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.
