I have troubles with a Styled TextArea and tabs

Thanks, Norman. My comment above was meant to be in keeping with what you’ve stated. That is, things that Xojo explicitly supports, there are properties and methods for; things Xojo doesn’t support, there aren’t. My suggestion was only that access be made easier to generic RTF control codes - that’s all that Xojo would be guaranteeing. What use one made of that power would be on that person (think Spiderman here).
