This'll be brief 'cause I don't have much time right now:
You remap keys from [something] to [something_else]. Right now you don't know what those keys are outputting. Until you know the [something] you can't remap those keys to [something_else].
I'm guessing you are using Soarer's Converter. Read the doc's, especially the "Codes" and "Trouble" sections. The tool you need is called HID Listen and it can be found
here.
Using HID Listen you can see what codes those keys are outputting and then remap them to what you want.
