I've tried agraham's example but nothing seemed to happen, is this just on my device
Anyway, attached is some code that I've written to overcome your little problem.
Basically I've hidden a panel with three labels representing the menu items.
Press the Enter hardware button to display the Menu.
Up and Down to scroll through the menu choices.
Enter again to select the highlighted menu item or Left to close the menu.
Alternatively you can add another level of menu which could be accessed using a Right click.
Hope you like it. If it was possible to draw lines on a panel then I could have made it even more like the real menu which by the way still works.
