So great helpful reply.. its point:

Need a workaround on issue that Wine does not (yet) support keyboard layout input else than the first one set or English: en_.. (not sure of the more precise) and an .exe app is almost 100% a native language of other than the 1st KB layout or en_US or alike

So switching to 2nd, so on, KB layout, a key pressed give no affect at all, if only the said app easily freely available it'd help by typing this tiny text editor in native Linux functionality i.e. able to get key input of any KB char. code then copy the text with mostly <70 chars into the input field point/event on that .exe app

So the snap feature clearly seems trivial, would benefit great as it 'd stick the note pad border allignedly at or inside the .exe's one
