 ### Operations
 
-| `!!` | Execute last command again |         
-| `!!:s/<FROM>/<TO>/` | Replace first occurrence of `<FROM>` to `<TO>` in most recent command |
-| `!!:gs/<FROM>/<TO>/` | Replace all occurrences of `<FROM>` to `<TO>` in most recent command |
-| `!$:t` | Expand only basename from last parameter of most recent command |
-| `!$:h` | Expand only directory from last parameter of most recent command |
+| Code                 | Description                                                           |

 `!!` and `!$` can be replaced with any valid expansion.
 
 ### Slices
 
-| `!!:n` | Expand only `n`th token from most recent command (command is `0`; first argument is `1`) |
-| `!^` | Expand first argument from most recent command |
-| `!$` | Expand last token from most recent command |
-| `!!:n-m` | Expand range of tokens from most recent command |
-| `!!:n-$` | Expand `n`th token to last from most recent command |
+| Code     | Description                                                                              |
