Show function signature while coding function?

Hi,

I have the brain of a nat. I admit it and I try to make it work for me by NOT remembering anything. (Don't you judge me! tee hee).

When I am coding a function that I am not familiar with I rely heavily on the function signature suggestions. In most editors, pressing crtl + space or ctrl+shift+space will restore the function signature popup. This works for me in Visual Studio, KDevelop Geany and Eclipse. But in CLion, the signature disappears shortly after I accept the initial suggestion and never comes back. *Sometimes*, if accept the initial suggestion and then leave my cursor sitting for FIVE SECONDS, then I see the function signature again briefly, but as soon as I start typing it disappears.

Please, is there some hotkey that I can use to recall the current function signature popup?
