Bug 19113 [Navigator] F2 for Rename in Navigator conflicts with Java Editor
The Navigator uses F2 for Rename, while the Java Editor defines F2 as "Show Tooltip Description". One of them needs to go. It's confusing because F2 does a Rename in the Navigator unless you have a Java Editor open, *even though* the Navigator view has focus. If you're used to using F2 to rename a resource in the Navigator, it will appear that the function is broken unless you know that the reason it's not working is because you have a Java Editor open. I know that accelerator keys are an unresolved issue in general, but at least the base Eclipse components should not conflict with each other.
