The arrow key is used by mny widgets for navigation, either within the widget data, or to navigate from one widget to another. For this reason, the arrow keystrokes rarely become available as a shortcut. If you *must* use the arrow keys as shortcuts, you have to teach all other keys in your user interface to not use the arrow keys. You have to derive your own class from every widget that uses arrow keys that may be active in your UI, and override the handle() method to not use arrow keys during the FL_KEYBOARD event. There is one other way to use the arrow keys, but not via the shortcut interface. For that, you derive your own button class and handle the arrow keys yourself during FL_KEYBOARD events. Now as long as no text input widget is active, your buttons will likely get the event first (at least before Fl_Group uses them for navigating between widgets).
