Hope it works.
By the way, did you decide to use a single finger one key press, or did you go for the ctrl + Key method.
The later two finger method is more often used for two reasons. 1, you have a lot more choices available, and 2, you can avoid some mistakes when you accidentally hit a single key.
For the benefit of others reading this. If you only need to exchange a few keys on the keyboard, that is called keyboard mapping ans is not the same thing as a macro key thing. The macro key does more that just give you a a key, it can start a program or insert a text. It can even emulate mousse movements. This is great for people with disestablishes.
