 #### Controlling `nnn`'s active directory
 `nnn` provides a mechanism for plugins to control its active directory.
 The way to do so is by writing to the pipe pointed by the environment variable `NNN_PIPE`.
-The plugin should write a single string in the format `<number><path>` without a newline at the end. For example, `1/etc`.
-The number indicates the context to change the active directory of (0 is used to indicate the current context).
+The plugin should write a single string in the format `<context number><char><path>` without a newline at the end. For example, `1c/etc`.
+The context number indicates the context to change the active directory of (0 is used to indicate the current context).
+The `<char>` indicates the operation type.
+
+: Char : Operation :
+|:---:| --- |
+| c | cd |
+| l | list files in list mode |
 
 For convenience, we provided a helper script named `.nnn-plugin-helper` and a function named `nnn_cd` to ease this process. `nnn_cd` receives the path to change to as the first argument, and the context as an optional second argument.
 If a context is not provided, it is asked for explicitly. To skip this and choose the current context, set the `CUR_CTX` variable in `.nnn-plugin-helper` to `1`.
