Weston Thayer commented on GUACAMOLE-1037:
------------------------------------------
Thanks for the context [~mjumper], that's really helpful. That's good to know
for the Belgian case. I'd assume the software would say "press Ctrl+W" if it
were localized since that's an easier combo to hit. One area I'm still hung up
on physical layout vs. what's printed on the keycap is the cross platfrom case
of MacOS -> Windows. As I mentioned, on an Apple Mac keyboard, {{OPTION/ALT +
M}} (or most other characters) is used to type a special character (like µ). If
I'm using a Mac as my client computer, but I'm remoting to Windows, it's not
uncommon for programs to use {{ALT + M}} as a keyboard shortcut. Due to
Guacamole's "local key identity dictates keyboard behavior" philosophy, I can't
access the {{ALT + M}} keyboard shortcut, because the Mac does not have an
equivalent "local key identity" for {{ALT + M}}.
Good point about the Shift behavior. I think that's controlled at the guacd
level, in the keymap files?

> Key: GUACAMOLE-1037
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-1037
> Project: Guacamole
> Issue Type: Bug
> Components: guacd
> Affects Versions: 1.2.0
> Reporter: andrea lattanzi
> Priority: Minor
>
> Hello!
> I was pushed to use guacd 1.2 after facing 1.1 huge memory leaks bug.
> The users signalled me this bug that could be workaround by running OSK on
> the remote.
> To log key events I used this site:
> [https://unixpapa.com/js/testkey.html]
> Now I'm pasting the results in several conditions of the following test
> sequence:
> 1) "a" key low case
> 2) caps lock
> 3) "A" key
> 4) caps lock
> 5) "a" key
> The client OS is Ubuntu, but OS and browser/version combinations don't look
> to affect the bug.
