@BeckyEbook,
When you get a free moment, please try with altgr in the command line with what I just pushed to master ...

Hopefully this change will make it somewhat more like Sigil-1.7 handling when altgr worked.

For those interested n what I added, here is the change just pushed to master to try to handle this case.
