i have been using the same config for a long time
bind-key -t vi-copy 'v' begin-selection
Recently I upgraded to Ubuntu 18.04 LTS. I start to receive this kind of error:
/home/user/.tmux.conf:13: usage: bind-key [-cnr] [-T key-table] key command [arguments]
Have you ever run into the same kind of problem?
tmux -V tmux 2.6
