There's an exception in editors (in edit mode) where these fillers may be displayed distinctly (but this is true for any other controls) It may be useful exactly in the situation where you've only partly entered a syllable block which still not conforms to the normal Hangul syllable syntax (which should always contain two characters, at least one leading consonnant or a filler, and at least one vowel or a filler, trailing consonnants jamos being optional but normally never occuring before the two other kind of characters in the standard syntax): a visible glyph may show to the user that the syllable is not complete. But if the editor is working in WYSIWYG mode only, nothing will be displayed in the document itself (but that visible control glyph may be shown within the IME input panel and inserted the document only when the syllable is complete).
