* (bug 2741) Adds support in the SDL client for many keys that were not

recognized.  For example, F13, F14, F15, WINDOWS, SCROLLLOCK, CAPSLOCK,
  WORLD_0 - WORLD_95, etc. (Christophe Cavalaria)

* (bug 2741) Adds the hard-coded toggleConsole bind Shift-Escape

+SDL Keyboard Differences
+  ioquake3 clients built againt SDL (e.g. Linux and Mac OS X) have different
+  keyboard behaviour than the original Quake3 clients.
+
+    * "Caps Lock" and "Num Lock" can not be used as normal binds since they
+      do not send a KEYUP event until the key is pressed again. 
+
+    * SDL > 1.2.9 does not support disabling "Dead Key" recognition.
+      In order to send "Dead Key" characters (e.g. ~, ', `, and ^), you
+      must key a Space (or sometimes the same character again) after the
+      character to send it on many international keyboard layouts.
+
+    * The SDL client supports many more keys than the original Quake3 client.
+      For example the keys: "Windows", "SysReq", "ScrollLock", and "Break".
+      For non-US keyboards, all of the so called "World" keys are now
+      supported as well as F13, F14, F15, and the country-specific
+      mode/meta keys.
+
+  SDL's "Dead Key" behaviour makes the hard-coded toggleConsole binds ~ and `
+  annoying to use on many non-US keyboards.  In response, an additional
+  toggleConsole bind has been added on the key combination Shift-Esc.
