Intellij code completion, showing method/constructor parameter types and variable names

Question

I find this extremely annoying that you often do not get help with figuring out the parameter signatures of methods and contructors when you have already written the first parameter.

Instead Intellij will show the variables available to you in your context. This is good, but not the first prio. I want to see the signature of the method/constructor as well.

This has the consequence that you always have to keep deleting and CTRL + SPACE to see the signature.

Is there a way around this issue?

You don't have to press Ctrl+P, you can configure IDEA to always show this information:

Go to Settings > Editor > General > Code Completion

Select the Show full signatures and Autopopup in (ms:) boxes.

Yeah, the ctrl-p is still useful when editing a method that already exists. – Software Engineer Oct 29 '14 at 21:37
Actually, it will disappear if this box is inactivated for some reason. You can get it back with CTRL + P – mjs Oct 29 '14 at 21:37

You can press Ctrl+P to show the signature(s) of the method/constructor, see this link for more details:
