Eclipse mark problems with this red underline, if one place the mouse curor above this line then an error description will pop up. — How can see that same error description for the text cursor?
The probelm/marker view is not the solution, because they will show all errors, and I need only the “current” error.
The solution must work without mouse!
You can move the text cursor over the error and press F2 which shows the error and offers solutions as well.
