The current View Text Symbols function is hopeless, since text symbols do not take any space in the display. Determining whether the cursor is to the right or left of a text symbol is trial and error. Multiple text symbols (e.g. index markings) in the same place show as one. There is little distinction between different types of text symbols.
Implement a display option that does not stick religiously to WYSIWYG but that shows text symbols in a usable manner!
