I'm just swapping from eclipse to IntelliJ, and I can't find this particular feature.
In Eclipse, when the cursor is inside the brackets of a method-call and I press Ctrl+Space, it tells me which parameters this method takes. Is there something similiar in IDEA?
Except CTRL+P (or CMD+P for Mac)
There is new feature in IntelliJ IDEA EAP:
Parameter name hints
Settings > Editor > General > Appearance
