Welcome!

I use multiple machines, so can't speak from personal experience, but I encourage you to trawl through the old posts here for more information.

This topic is touched upon in throughout the board, and specifically in one of the sticky posts here. The most popular solution seems to revolve around a program called Autohotkey, described in detail here.

There is some discussion about how close this software comes to crossing that oh-so-grey line of "third party software".

Good luck, and happy boxing!
