+  input.c
+
+  Handles keypad (and other?) input from the user.
+
+  Currently, the keys are as follows:
+
+  Context     Key      Function
+  -------     ---      --------
+  Normal               "normal" context is handled in this source file.
+              A        Pause/Continue
+              B        Back(Go to previous screen)
+	      C        Forward(Go to next screen)
+	      D        Open main menu
+              E-Z      Sent to client, if any; ignored otherwise
+
+ (menu keys are not handled here, but in the menu code)
+  Menu
+              A        Enter/select
+	      B        Up/Left
+	      C        Down/Right
+	      D        Exit/Cancel
+	      E-Z      Ignored
