tmux/cmd-unbind-key.c
nicm bded743706 Support for multiple key tables to commands to be bound to sequences of
keys. The default key bindings become the "prefix" table and -n the
"root" table. Keys may be bound in new tables with bind -T and
switch-client -T used to specify the table in which the next key should
be looked up. Based on a diff from Keith Amling.
