As I'd like to use my tablet as a "thin-client" i.e. desktop terminal to my server, I need keys like "return" to act as "escape" and "lock" as "delete" etc. So I changed the mappings in "/system/usr/keylayout/asuspec.kl".
In the case someone else would be interested in remapping their keyboard, I have compiled a list of scan-codes associated with each physical key.
This though with the exception of the "Fn" key, which I suspect function on a purely hardware based level to alter key scan-codes.
This list is based on a "nordic" layout (not sure if physical layout differs?), but I refer to each key as R#C#, row number and column number, starting from 0.
Hope this is going to save someone some time
