+\r
+Abstract:\r
+\r
+ This file produces the Simple Text In for an Gop window.\r
+\r
+ This stuff is linked at the hip to the Window, since the window\r
+ processing is done in a thread kicked off in WinNtGopImplementation.c\r
+\r
+ Since the window information is processed in an other thread we need\r
+ a keyboard Queue to pass data about. The Simple Text In code just\r
+ takes data off the Queue. The WinProc message loop takes keyboard input\r
+ and places it in the Queue.\r
