+Each action will return a success flag. Actions can be chained such that
+the chain only continues when there are successes, or failures, or either.
+The `,` separator will always chain to the next action. The `|` separator
+will abort the chain if the action preceding it succeeds, and the `&` will
+abort the chain if the action preceding it fails. For example, in the default
+bindings, tab is bound as
+
+```
+"Tab": "Autocomplete|IndentSelection|InsertTab"
+```
+
+This means that if the `Autocomplete` action is successful, the chain will abort.
+Otherwise, it will try `IndentSelection`, and if that fails too, it will
+execute `InsertTab`.
+
+## Binding commands
+
+You can also bind a key to execute a command in command mode (see
+`help commands`). Simply prepend the binding with `command:`. For example:
+
+```json
+{
+ "Alt-p": "command:pwd"
+}
+```
+
+Now when you press `Alt-p` the `pwd` command will be executed which will show
+your working directory in the infobar.
+
+You can also bind an "editable" command with `command-edit:`. This means that
+micro won't immediately execute the command when you press the binding, but
+instead just place the string in the infobar in command mode. For example,
+you could rebind `CtrlG` to `> help`:
+
+```json
+{
+ "CtrlG": "command-edit:help "
+}
+```
+
+Now when you press `CtrlG`, `help` will appear in the command bar and your cursor will
+be placed after it (note the space in the json that controls the cursor placement).
