Loose the quick editor (ctrl-shift-e) and its content when mouse gets out of the quick editor window or when I hit ctrl-space. I dont know if ctrl-space is suppose to serve in the quick editr but I do hit that key a lot by reflex because it normally is the code completion in intellij.
At least conserve the content of the quick editor (save it in the java string).
The mouse close quick editor when it touch some red text (text with error) or their red bars at the right of the quick editor.
