class Fl_Return_Button : public Fl_Button

A return button has a built-in shortcut for the Enter key. Typing the Enter key generates the callback(). Otherwise it acts like a normal Fl_Button. It will draw with an arrow to indicate that the Enter key works.

The shortcut will not work if a Fl_Multiline_Input or other object that absorbs Enter FL_KEYBOARD events has the focus.
