    'tmux' was made to let people work in console without using a mouse.
    Ideally, to do everything without even touching a mouse at all and
    always keep their fingers on 'A' 'S' 'D' 'F' and 'J' 'K' 'L' ';'
    keys.
    Like when you use 'vim' (or 'nano' in your case), you just type and
    use memorized key combinations to perform actions on text, buffers,
    etc, and in case of 'tmux' , on text inside multiple panes.
    Personally, I've failed to memorize all the commands of 'tmux' and
    'vim' and "be efficient and fast without a mouse", as it says on a
    tin.
    But I've managed to remember a few major ones and still enjoy
    working inside several consoles on a single screen and do that quite
    frequently.
    
    AFAICR I had to personalize configurations for both 'tmux' and 'vim'
    , so they would use clipboard of X server instead of their own
    buffers.
    I can use mouse to select and copy lines of text in linear or in
    rectangular fashion:
    Rectangular fashion:
        Hold Shift + Hold Ctrl + Press and hold LMB at the beginning of
    the text you want to copy;
        Move mouse to select wanted text lines and release LMB;
        Click LMB on the selected text and then release Shift and Ctrl
    keys.
    
    Linear fashion:
        Hold Shift + Press and hold LMB at the beginning of the text you
    want to copy;
        Move mouse to select wanted text lines and release LMB;
        Click LMB on the selected text and then release Shift key.
    
    Linear fashion for a single 'tmux' pane:
        Press and hold LMB at the beginning of the text you want to
    copy;
        Move mouse to select wanted text lines and press 'y' key;
        Then release LMB.
    
    To paste copied text press "Ctrl + v" or "Shift + Ctrl + v" or
    "Shift + Insert" or "Shift" + "p" (if you would use 'vim').
    If my directions work differently for you, here I've tried to
    gather, hopefully, relevant config lines from my "~/.tmux.conf":
    
    ========8<============8<============8<============8<====
    ## Mouse mode enabled by default
    set -g mouse on
    ## Use vi control scheme by default
    set-window-option -g mode-keys vi
    ## Use system buffer for copy paste operations in tmux
    bind-key -T copy-mode-vi v send-keys -X begin-selection
    bind-key -T copy-mode-vi y send-keys -X copy-selection
    bind -T copy-mode-vi y send-keys -X copy-pipe "xclip -sel clip -i"
    bind P paste-buffer
    bind-key -T prefix PageUp copy-mode -eu
    bind-key -T prefix PageDown copy-mode
    ========8<============8<============8<============8<====
    
    Btw, keys 'v' (visual mode select) 'y' (copy text) and 'P' (paste
    text) are for the same actions in 'vim' , so they are easier to
    remember.
    Also, I use Xfce and "xfce4-terminal" so my instructions may not
    work if your DE is different.
