This event occurs when the cursor leaves the visible portion of a Text Control's client area whilst a text selection is being expanded with the mouse. It is only sent if the cursor movement does not result in a caret movement. This happens if the cursor is moved outside the client area or if the cursor is moved over parts which are not covered with text below the last line. In all cases where the cursor movement results in a caret movement, the Text Control sends CaretOutxxx events. This event occurs only if the ViewMode property has been set to Simple Control.
