I am running arch linux with plasma and in a konsole (version 19.12.3-1) window left arrow should be replaceable by ctrl-B in bash - but ctrl-B does nothing. Is there a way to get this working? Or is it s bug in the current version of konsole for bash keyboard shorcuts? The other similar shortcuts like alt-B, ctrl-F and alt-F do work and it is only ctrl-B that doesn't.
