appendText() — Appends the specified text to the end of the RichEditableText, as if you had clicked at the end and typed it. When RichEditableText supports vertical scrolling, it will scroll to ensure that the last line of the inserted text is visible.
insertText() — Inserts the specified text as if you had typed it. If a range was selected, the new text replaces the selected text; if there was an insertion point, the new text is inserted there, otherwise the text is appended to the text that is there. An insertion point is then set after the new text.

The following example(s) require Flash Player 10 and the Adobe Flex 4 SDK. To download the Adobe Flash Builder 4 trial, see http://www.adobe.com/products/flex/. To download the latest nightly build of the Flex 4 SDK, see http://opensource.adobe.com/wiki/display/flexsdk/Download+Flex+4.
