Thank you for you answer.
I just tried your combination - yes it does compile my project. But. It compiles significantly slower. For example - when I select GWT compile project from toolbar - then compilation time is between 13 - 15 seconds. When I press Ctrl + F11 and select "Compile GWT application" then compilation takes 23 - 29 seconds. Yes - its almost 2 times longer.
I think it is connected with my compilation parameters which I specify in compilation dialog box (which shows up only when I select GWT compile with my mouse). I think when I press shortcut - compiler simply ignores my "-draftCompile" settings.
If it matters - I use GWT 2.5rc for compilation.
