callback Ef
is one of an enumerated set. The association to keys on your keyboard should be obvious. Their GLUT symbol names are:

GLUT_KEY_F3 Ef

- Bf Sy

current window Ef
.

CAVEATS

Many keys are not included; nor is it possible to apply qualifiers such as the Shift or Ctrl key to these keys.

Windows created via glutCreateMenuWindow() always cascade keyboard and mouse events to their parent.
