I don't know for sure if it's a bug or a feature, but in the latest snapshot, F3+Q reloads all chunks and F3+A shows the list of debug keybindings.
This is inverted in 1.12.2
And no, it's not because my keyboard is in the wrong azerty/qwerty mode. I checked that.

Found the issue I was thinking of: MC-121278, "Keybindings (p.g. Ctrl+A) are being mapped to the US keyboard layout even if you're using another layout"
migrated
thats possible, my keyboard is azerty
but when using the chat etc. it all works fine
Still, what layout is your keyboard in? Is it an azerty keyboard? I somewhat remember there being a report about the game using the wrong layout.
