+If SEQUENCE is the empty string, i.e. an empty set of quotes, this is
+interpreted as the default keybinding. It will be used whenever no
+other binding matches. For most key bindings, it makes sense to use
+the \c self-insert function (i.e. <tt>bind '' self-insert</tt> as the
+default keybining. This will insert any keystrokes not specifically
+bound to into the editor. Non-printable characters are ignored by the
+editor, so this will not result in e.g. control sequences being
+printable.

 If the -k switch is used, the name of the key (such as down, up or
 backspace) is used instead of a sequence. The names used are the same
 as the corresponding curses variables, but without the 'key_'
 prefix. (See man 5 terminfo for more information, or use <tt>bind
---names</tt> for a list of all available named keys)
+--key-names</tt> for a list of all available named keys)
 
 COMMAND can be any fish command, but it can also be one of a set of
 special input functions. These include functions for moving the
 cursor, operating on the kill-ring, performing tab completion,
-etc. Use 'bind -N' for a complete list of these input functions.

 When COMMAND is a shellscript command, it is a good practice to put
 the actual code into a <a href="#function">function</a> and simply
-bind to the function name.
