The text display class provides a general means for text entry. It can be used wherever a note pad is needed in applications. Any character vector can be displayed in this class. Once an object of this class has focus, editing can begin. New lines are created during text entry by pressing the Enter key, which then appears in the character vector as the character `char©10 (newline); this is the only control character that should be used in the text. APL characters can be entered.Attributes
There are no user actions that begin and end edit mode; consequently, when the text is entered the underlying character vector may not be automatically updated (see the save attribute). However, even if the character vector is not updated, the current text on the screen can be obtained as the value of the buffer attribute.
