+/**
+    @descr  implements a helper, which can be used to
+            convert vcl key codes into awt key codes ...
+            and reverse.
+
+            Further such key code can be triggered.
+            Doing so different accelerator
+            configurations are merged together; a suitable
+            command registered for the given key code is searched
+            and will be dispatched.
+
+    @attention
+
+            Because execution of an accelerator command can be dangerous
+            (in case it force an office shutdown for key "ALT+F4"!)
+            all internal dispatches are done asynchronous.
+            Means that the trigger call doesn't wait till the dispatch
+            is finished. You can call very often. All requests will be
+            queued internal and dispatched ASAP.
+
+            Of course this queue will be stopped if the environment
+            will be destructed...
