EXAMPLES:
~~~~~~~~~
1. To use as hotkey on Toshiba laptop:

Search (using DOS program) CLIPLIB.DLL for:
F6 46 F6 38 ; TEST Byte Ptr [BP-0A], KC_SHIFT | KC_ALT | KC_CTRL

and change to:
F6 46 F6 30 ; TEST Byte Ptr [BP-0A], KC_ALT | KC_CTRL

2. To use instead of as the hotkey:

Search CLIPLIB.DLL for:
83 7E F8 19 ; CMP Word Ptr [BP-08], VK_PRINTSCRN

and change to:
83 7E F8 2B ; CMP Word Ptr [BP-08], VK_F12
