Hi, I can not find how to check the help page of a function.

For example, I want to check the help page of "head". How should I do it? (":help" doesn't seem to help.)

`:t head` will show the function signature (which in 90% of the cases is more than enough to understand what the function does). `:i function` will show the function signature and additionally tell you in which module it is defined.
