| `%{dirname}` | The absolute path of the parent directory of the currently focused file. |
| `%{cwd}` | The absolute path of the current working directory of Helix. |
| `%{linenumber}` | The line number where the primary cursor is positioned. |
| `%{selection}` | The text selected by the primary cursor. |
| `%sh{cmd}` | Executes `cmd` with the default shell and returns the command output, if any. |
