The Maple 10 Help on Embedded Component provides examples for all components that I have found to be easy to follow and understand except for the example relating to the Text Area component. With this example, one should be able to perform the action of retrieving an expression entered in a text area and displaying this expression as 2-D Math in a math container upon selecting Enter. The instruction to perform this action is to enter the following in the Action When Contents Change field of the Text Area. This instruction is: SetProperty 'MathContainer0', 'value',parse(GetProperty('TextArea0', 'value')));
