That will allow you to toggle between the US and FR keyboard layouts
by simultaneously pressing Alt + Shift
You could also install this fbxkb-0.4-i486-startup-1.pet
which will give you a visual indication as to what layout you are using by way of a flag in the taskbar,
you can also toggle between the two layouts by clicking on the flag.
After editing the Xorg conf file i was able to use the Alt+Shift combo to change the language but in Write it will give strange fonts (unreadable) if i choose other than US , in Calc and Paint it is ok.
I opened the Write conf file but it was very huge i was lost .
Can the Write config file be edited?? and if yes: how ?
One last thing : the fbxkb-0.4-i486-startup-1.pet did not work with all Puppy versions i have.
