+a key packet, as returned by the kernel, is a 32-bit value. the top
+13 bits are currently reserved. the next 11 bits are flags as follows:
+  0x040000: break (as opposed to make)
+  0x020000: num lock is on
+  0x010000: caps lock is on
+  0x008000: right windows
+  0x004000: left windows
+  0x002000: right alt
+  0x001000: left alt
+  0x000800: right ctrl
+  0x000400: left ctrl
+  0x000200: right shift
+  0x000100: left shift
+the bottom 8 bits represent the key. for us qwerty, they are:
