+Classic : Keeps all standard keys on US QWERTY and adds customizations via the `Right Alt (+Shift)` modifier.
+
+SW (switched) edition : Adds customizations via the `Right Alt (+Shift)` modifier, but makes the symbols !, @, #, $, %, ^, &, \*, ( and ) accessible without holding down Shift. The numbers have moved to Shift (as most computers also have a separate numpad).

+## Script for AutoHotkey (Windows)
+
+This AutoHotkey script is a highly customizable version of UltimateKEYS. To work properly, the Windows keyboard has to be set to standard US QWERTY and at least AutoHotkey v1.1 (preferably as 'Unicode 64-bit', on 32-bit Windows as 'Unicode 32-bit') is required.
