How to make reappear the info of a function

[dr-costas]

Hi,

When you are in INSERT mode and typing a function, e.g. foo with arguments a and b, i.e. foo(a, b), then you have the pop-up info with information like:

foo(a: ..., b: ...)

right after you press the parenthesis. But, if you press any button afterwards, e.g. return, then this pop-up goes away. How can one make it reappear?
