Indeed, I tried that and it works!

Something as simple as:

(global-unset-key [down-mouse-3])
(global-set-key [mouse-3] context-menu-entry)

seems to work; but maybe Juri made the other one the default for some
reason.

Any way I agree that this behavior is more comfortable and probably
should be the default. But at least this needs a custom or to be
documented for new users.

I would do something more or less like:

(defcustom context-menu-mode-binding [down-mouse-3]
           "BLABLA")

(...)
(context-menu-mode
    (setq context-menu--old-mouse-3 (global-key-binding [mouse-3]))
    (setq context-menu--old-down-mouse-3 (global-key-binding [down-mouse-3]))
    (global-unset-key [mouse-3])
    (global-unset-key [down-mouse-3])
    (global-set-key context-menu-mode-binding context-menu-entry))

Apart from that, there is another issue with the "Paste" command in tty.

Paste calls mouse-yank-primary, but in tty this commands calls
gui-get-primary-selection and there is no selection because it tries to
get the one on the primary selection not the one in the system
(secoundary or clipboard) not the emacs kill-ring either.

So I get: error("No selection is available")
