 - ``--preset`` and ``--user`` specify if bind should operate on user or preset bindings. User bindings take precedence over preset bindings when fish looks up mappings. By default, all ``bind`` invocations work on the "user" level except for listing, which will show both levels. All invocations except for inserting new bindings can operate on both levels at the same time. ``--preset`` should only be used in full binding sets (like when working on ``fish_vi_key_bindings``).

 Special Case: The escape Character
-------------
+----------------------------------
 
 The escape key can be used standalone, for example, to switch from insertion mode to normal mode when using Vi keybindings. Escape may also be used as a "meta" key, to indicate the start of an escape sequence, such as function or arrow keys. Custom bindings can also be defined that begin with an escape character.
