# * `target` An `HTMLElement`
# * `options` See http://getbootstrap.com/javascript/#tooltips for a full list
# of options. You can also supply the following additional options:
# * `keyBindingCommand` A {String} containing a command name. If you specify
# this option and a key binding exists that matches the command, it will
# be appended to the title or rendered alone if no title is specified.
# * `keyBindingTarget` An `HTMLElement` on which to look up the key binding.
# If this option is not supplied, the first of all matching key bindings
# for the given command will be rendered.
#
# Returns a {Disposable} on which `.dispose()` can be called to remove the
# tooltip.
