Yeah, the first one is called `bind`. The second one is a variety of `bind`. But you can just lookup the symbol in Hoogle and it will give you the definition.

You can also lookup a type signature and Hoogle will give you all functions for that type signature. For example, there is only one total function `(a -> b) -> [a] -> [b]` (map) and if you search that Hoogle will show you map, accordingly: https://www.haskell.org/hoogle/?hoogle=%28a+-%3E+b%29+-%3E+%5Ba%5D+-%3E+%5Bb%5D https://www.haskell.org/hoogle/?hoogle=%28a+-%3E+b%29+-%3E+%... Honestly Hoogle for Haskell is better than Google for other languages for finding things. EDIT: Oh, you can also click to go to the operator docs. For the case of <$>, the docs would tell you that it's an fmap synonym.
