An easier way to type accented uppercase characters on AZERTY chromebooks?

[A]

Hi all, 

Currently, to write accented uppercase characters on a AZERTY keyboard, you have the choice to use unicode 

À : Ctrl-Shift-U then 00C0

Ç : Ctrl-Shift-U then 00C7

É : Ctrl-Shift-U then 00C9

Ê : Ctrl-Shift-U then 00CA

....

Not very useable.

The second choice is to use an UTF8 extension, and to  manually pick the accented characters. Not very quick

I daily use linux systems and the keyboard is'nt settle this way. 

To write "À"  you press caps lock then  the "à" key , É with caps lock then "é"  key, È Ç Ù , etc

I guess that if it works with linux it should works with chromebook

Could it be possible to change the keyboard mapping for the AZERTY users? I know there is no caps lock key but the alt + search shortcut could ease a little 

This would be very useful for these users who have to comply  with high level spelling

Thanks
