perWindowKeyRepeat :: StateVar PerWindowKeyRepeat
GLUT Graphics.UI.GLUT.DeviceControl
Controls if auto repeat keystrokes are reported to the current window. Ignoring auto repeated keystrokes is generally done in conjunction with using the keyboardMouseCallback. If you do not ignore auto repeated keystrokes, your GLUT application will experience repeated release/press callbacks. Games using the keyboard will typically want to ignore key repeat.
