Intellisense typically pops up when I open the '(' on a function call showing the data types of the parameters matched, allowing you to hit up or down to see all possibilities of overloaded function calls.
Is there a keyboard shortcut to force this to happen if I move cursor focus outside the function call and want to see it again?
Ctrl+Shift+Space shows the parameter information..
