View Parameter Info

Quickly see function arguments and argument types.

See what's needed in a function, as you type, without disruption.

Have a function with lots of arguments? Parameter Info gives just the basics without using lots of real estate.

In Depth

Some functions or classes -- well, let's admit it, they are kind of chatty. They require lots of arguments, have lots of optional keyword arguments, some with default values.

So you stop, go look at the function, and come back to what you were doing.

There's a better way. With your cursor in the parentheses, invoke Parameter Info (Ctrl-P Win/Linux, Cmd-P macOS.) You get a tiny popup with the positional and keyword arguments, along with any default values. Bold is used to mark the current spot in the parameter list that your cursor is at.

You can invoke this before you type any parameters, after you've typed a few, or later if you come back to make a change.
