Description From cendio 2019-10-31 12:43:35
We improved the AltGr handling in bug 5226 for the native client. Similar work
was done upstream for noVNC:

https://github.com/novnc/noVNC/pull/1035

And got merged in to Web Access via bug 6152.

However Ctrl+AltGr is still broken in IE and Edge, so there is some detail
missing.

The reason this works in Firefox and Chrome is because they do the AltGr
detection for us and send 'AltGraph' as the key. IE and Edge aren't as friendly
and send 'Alt' instead.

TigerVNC solves this by examining the keyboard layout. Unfortunately we cannot
do the same here as there is no API to do that.

Let's close this bug as there isn't anything more we can do at the moment, and
hopefully this corner case will not affect any real users as it is doesn't
affect Firefox or Chrome.

This was fully tested on bug 6152, so closing.
