+ * NOTE: The AT/MF keyboards can generate (via the 8042) two (MF: three)
+ * sets of scancodes. Set3 can only be generated by a MF keyboard.
+ * Set2 sends a makecode for keypress, and the same code prefixed by a
+ * F0 for keyrelease. This is a little bit ugly to handle. Thus we use
+ * here for X386 the PC/XT compatible Set1. This set uses 8bit scancodes.
+ * Bit 7 ist set if the key is released. The code E0 switches to a
+ * different meaning to add the new MF cursorkeys, while not breaking old
+ * applications. E1 is another special prefix. Since I assume that there
+ * will be further versions of PC/XT scancode compatible keyboards, we
+ * may be in trouble one day.
+ *
+ * IDEA: 1) Use Set2 on AT84 keyboards and translate it to MF Set3.
+ * 2) Use the keyboards native set and translate it to common keysyms.

-** FIXME FIXME FIXME - web key code to scan code mapping
-** This is really atrocious code. At the end of the day, we need to
-** map keystrokes generated by the browser into the scan codes required
-** by spice. This table was literally built by me pressing keys on my keyboard
-** and typing the resulting value in by hand.
-** I'm sure Europeans will hate me, and the Chinese will likely *never*
-** talk to me.
+** Converting keycodes to AT scancodes is very hard.
+** luckily there are some resources on the web and in the Xorg driver that help
+** us figure out what browser dependent keycodes match to what scancodes.
+**
+** This will most likely not work for non US keyboard and browsers other than
+** modern Chrome and FireFox.
