DoubleCommand Alternatives: Finding the Best Keyboard Remapping Software
DoubleCommand is software for Mac OS X (a kernel extension) that lets you remap keys, in other words change the way your keyboard works. Often used to make a PC keyboard more comfortable with a Mac, swapping the Alt (Option) and Windows (Command or Apple) keys, since they are in swapped positions on Mac and PC keyboards. DoubleCommand is a quick and easy way to fix this if you use a PC keyboard with your Mac. However, if you're looking for a DoubleCommand alternative for various reasons, whether due to platform compatibility or specific feature needs, there are excellent options available.
