Thank you for having solved the accented letters in the french azerty layout.
I detected that altgr +5, which should return [, returns {, like altgr+4 does.
It does it when using the rev7 as a writerdeck, but is ok when using the rev7 as a BT keyboard.
It is not a major problem, but I will use some markdown in my files in order to integrate some of my MJ files into an obsidian vault.
Thank you if you have time for this.
