 ## Using variables in typed commands and mapped shortcuts
 Helix provides several variables that can be used when typing commands or creating custom shortcuts. These variables are listed below:
 
-| Variable              | Description |
-| ---                   | ---                      |
-| `%{basename}`         | The name and extension of the currently focused file. |
-| `%{dirname}`          | The absolute path of the parent directory of the currently focused file. |
-| `%{cwd}`              | The absolute path of the current working directory of Helix. |
-| `%{git_repo}`         | The absolute path of the git repository helix is opened in. Fallback to `cwd` if not inside a git repository|
-| `%{filename}`         | The absolute path of the currently focused file. |
-| `%{filename:rel}`     | The relative path of the file according to `cwd` (will give absolute path if the file is not a child of the current working directory) |
-| `%{filename:git_rel}` | The relative path of the file according to `git_repo` (will give absolute path if the file is not a child of the git directory or the cwd) |
-| `%{ext}`              | The extension of the current file |
-| `%{lang}`             | The language of the current file   |
-| `%{linenumber}`       | The line number where the primary cursor is positioned. |
-| `%{cursorcolumn}`     | The position of the primary cursor inside the current line. |
-| `%{selection}`        | The text selected by the primary cursor. |
-| `%sh{cmd}`            | Executes `cmd` with the default shell and returns the command output, if any. |
