I love the tooltip popup that occurs when you enter the opening parenthesis for any function. ie: "my_function(" then you get the popup with the list of arguments and a little description of the function if provided.

It would be very useful if there was a way to trigger this on demand (right-click context menu option, keyboard shortcut, etc.) instead of having to type in the function anew any time you wanted to quickly see a description for the function. This would be useful for code that you are investigating and trying to figure out what existing function calls are doing.

Hi Mike. Go to Settings -> Editor -> Editor Shortcuts. Then, under Code Insight, find "Code tooltip". You can now set up your shortcut. I personally use the escape key to trigger this functionality. You can get this by using 'Esc' as a shortcut. Very convenient!
