from my `/etc/tmux.d/keyboard-shortcuts-comfort.conf`:

    bind-key j command-prompt -p "vim:" "new-window -c '#{pane_current_path}' 'stty -ixon -ixoff && vim %1'; select-pane -T '%1'"

This binds `j` to prompt for files to open (* or just hitting enter works) and launches vim in a new window in tmux (turning off flow control and setting filename as title). Probably one of my most-used shortcuts.
