os/tmux/ TmuxConfig

The config goes in ~/.tmux.conf. Mine is currently

setw -g mode-keys vi
bind-key -n C-PageUp previous-window
bind-key -n C-PageDown next-window
bind-key -n S-PageUp switch-client -p
bind-key -n S-PageDown switch-client -n

See here for more in vi mode. To see keybindings for vi mode, use list-keys -T copy-mode-vi.
