I'm not sure if this is a bug or a difference in configuration between v19 and v20. Possibly default configuration.
In Brief mode do the following:
- Highlight some text (ALT-L and cursor up or down will do this)
- Copy the text to the clipboard (Numeric Keypad Plus will do this)
- Go to the end of the document (END-END-END will do this)
- Insert the copied text (The insert key will do this)
The inserted text will be highlighted.
