We do not have the "CTRL+A" ?? ( see the edit )

Hello team !

I've a probleme I don't have the "CTRL+A" to copy the text I wrote in the chat bar ( Edit : I found the problem It's because I have an azerty keyboard so I have to do it with the Q key ( qwerty keyboard ) ! There is a way to do something ? )

and
" shift + / " has been shifted a key ( "shift + §" )?!
( Edit :  I found the problem it's just that it's not by default the slash in the control options)

Thank you in advance !
( sorry for my English ! )
