TechKeys Business Card Keyboard Program help

[OMQ12]

I'm Planning on getting a TechKeys Keyboard card ( http://techkeys.us/collections/accessories/products/techkeys-keyboard-business-card)  so I can play a game call "osu!" but I sure when I get it I wont know what to do with it. I saw the video demonstrating that it types links to there FB account, email, and website. They said they are reprogram-able but I dont want to buy it and dont know what to do. I would appreciate it if anyone were to tell me the EXACT steps, Make a video, or Make a ready made software for these buttons (escape,z,x) In that order. Thanks

I'm not an expert on these things, but I think you should
1. download the source.
2. edit the right file to change the keymap (techkeys.c looks to be a good choice.) change that whole macro into whatever key you want.
3. download the compiler for your OS (the windows one is linked)
4. compile it
5. flash it to the card using the instructions in komars post.

For what its worth I'm planning on supporting it with my firmware, which is much easier than compiling it yourself
