In a dialog, hitting the Enter key automatically presses the default button, usually the Ok button. This is the way the dialog manager works.
It almost all circumstances it is not a good idea to interfere with that. Windows users come to depend on that behavior.
With a single-line edit control, if the user hits Enter the default button is pressed. In some rare cases, I would like to catch that Enter and invoke a method in the Rexx dialog. It would be nice to have some way, a easy way, to do that.
