912 - Impossible to remap keys

[NicolasR]

Hi !

It seems to be impossible to remaps the keys on the 912 Pro (Fw : 2.1.2). The settings made in the Configurations menu, for the keys, are never stored, and the device keeps using the factory keys settings.
I have found a system/config/global.cfg file, wich have settings for the keys. Should I edit it directly ?
Here are the lines :

pkey.10.0=@KA_menu
pkey.10.1=@KA_none
pkey.17.0=@KA_zmin
pkey.17.1=@KA_none
pkey.18.0=@KA_none
pkey.18.1=@KA_olnk
pkey.19.0=@KA_prev
pkey.19.1=@KA_pr10
pkey.20.0=@KA_next
pkey.20.1=@KA_nx10
pkey.21.0=@KA_volm
pkey.22.0=@KA_volp
pkey.23.0=@KA_cnts
pkey.23.1=@KA_hist
pkey.24.0=@KA_prev
pkey.24.1=@KA_pr10
pkey.25.0=@KA_next
pkey.25.1=@KA_nx10
pkey.26.0=@KA_mmnu
pkey.26.1=@KA_none
pkey.27.0=@KA_exit
pkey.28.0=@KA_none
pkey.28.1=@KA_none
pkey.29.0=@KA_none
pkey.29.1=@KA_none
pkey.30.0=@KA_none
pkey.30.1=@KA_none
pkey.6.0=@KA_zout
pkey.7.0=@KA_zmin
pkey.8.0=@KA_none
pkey.8.1=@KA_none

There are these lines too :

tkey.10.0=@KA_menu
tkey.10.1=@KA_mmnu
tkey.17.0=@KA_pgup
tkey.17.1=@KA_olnk
tkey.18.0=@KA_pgdn
tkey.18.1=@KA_nnot
tkey.19.0=@KA_prev
tkey.19.1=@KA_pr10
tkey.20.0=@KA_next
tkey.20.1=@KA_nx10
tkey.21.0=@KA_volm
tkey.22.0=@KA_volp
tkey.23.0=@KA_cnts
tkey.23.1=@KA_hist
tkey.24.0=@KA_prev
tkey.24.1=@KA_pr10
tkey.25.0=@KA_next
tkey.25.1=@KA_nx10
tkey.26.0=@KA_mmnu
tkey.26.1=@KA_none
tkey.27.0=@KA_exit
tkey.28.0=@KA_none
tkey.28.1=@KA_none
tkey.29.0=@KA_none
tkey.29.1=@KA_none
tkey.30.0=@KA_none
tkey.30.1=@KA_none
tkey.6.0=@KA_zout
tkey.7.0=@KA_zmin
tkey.8.0=@KA_none
tkey.8.1=@KA_none

What is the difference between pkey et tkey ?
Thank you very much for your help !
