Remapping modifier keys to imitate Mac layout

To remap the sequence of the modifier keys in the lower left corner of the keyboard from Ctrl/Win/Alt to Win/AltGr/Ctrl (imitating the Mac layout of Control/Option/Command), use SharpKeys to remap the following:

From:	To:
Special: Left Alt (00_38)	Special: Left Ctrl (00_1D)
Special: Left Ctrl (00_1D)	Special: Left Windows (E0_5B)
Special: Left Windows (E0_5B)	Special: Right Alt (E0_38)
Special: Right Alt (E0_38)	Special: Left Alt (00_38)
