Alt keybindings interference with Alt-gr in international layouts

Describe the bug / provide steps to reproduce it

On some keyboard layouts, such as most English/International variants and many local ones (Spanish, for example), left and right Alt are differentiated: Left Alt for commands, and Right Alt (or "Alt Gr.") for accessing a third and fourth layout levels for many symbols.

Currently, Alt-a, Alt-o, Alt-i... produce the desired third level symbols (áóí in English International), but Alt-e is by default binded to go to next error in Acode. This binding is sticking not only to the regular left alt, but also interfering with the right alt, making it impossible to type Alt-e (é).

The binding system should respect the differentiation, binding to Left Alt only in layouts where Right Alt is used as Graphical Alt.

System keyboard or External Keyboard?

External Bluetooth keyboard. I'm not aware of any software keyboards that do the two differentiated alts.

Can you try this issue here -> https://codemirror.net/try/ @irisdominguez ? As we are in a process to fully migrate our Core Editor Library from Ace Editor to CodeMirror 6.

Sorry for taking long to answer! I checked, and Alt-E is not binded to anything on that demo. But Alt-l is binded (select whole line, apparently), and it seems to disntinguish them properly: Alt-gr-L produces a local variant of the L, and Alt-L selects the whole line.

So, hopefully, the new core library should solve this! I'm closing it and will reopen if it happens in that new version as well.

Could you point me to the branch / issue / PR where I could monitor the progress in the migration, if there's one?
