Keyboard Shutdown when typing "@"

With my german keyboard i want to write a "@" in keybase chat. On a german keyboard this is done by CTRL+ALT+Q. If I do that. the program will shutdown because CTRL+Q is the combination to shutdown. The correct way would be ALT GR + Q which is really counter intuitive to a german. I couldn't find a way to change that. Is there a way to set this? I really feel uncomfortable using Keybase, if this systematically happens. Thanks in advance!

No source files or tests are named in the report. Start by reproducing the shutdown when entering "@" with a German keyboard in Keybase chat, then trace how the Ctrl+Q shortcut is handled and how AltGr input is reported. Done means typing "@" no longer shuts down the program while the shutdown shortcut remains usable.
