Broken Intention Actions Dialogue when using non-standard (remapped) cursor moving keys

I have my keys mapped in a fashion similar to emacs/vim for cursor movement. When I hit the keystroke to bring up the intention actions dialogue (Alt-Enter) the keystroke I use to execute Editor->Actions->Down or Editor->Actions->Up does nothing, but using the arrow key moves the selector down/up appropriately. The class/variable autocomplete dialogue does behave correctly, which leads be to believe this is a bug. It did not bother me till the default for undefined variables switched from "Initialize with a value" to "Declare global", then it became personal! Is this a real bug?
