A friendly workaround for mode and meow state specific keymaps

[A7R7]

In this pull request the author of meow says

these cases are what I'm trying to avoid:

• configure meow for every major/minor modes
• removing meow = giving up the effort you spend to organize your keybinding
• introducing meow = rebuilding your keybind system

It seems meow would not support a binder like meow-normal-define-key :keymap xxx. The author also showed us the more emacs friendly way to bind mode specific keybinds to meow's keypad: bind C-x xxx to that mode map.

However, that's not complete. What if I want to bind some mode-specific keybinds in meow's normal/insert/motion mode?

I actually find out a workaround to do this. The idea here is as well bind keys directly in a major mode map, but with a keybind you'll never use as a prefix key. This prefix key serves as a "bridge" connecting meow and the rest of emacs.

As an example, I'll show how to bind C-j, C-k to org-next-visible-heading org-previous-visible-heading in meow-normal in org mode map. For simplicity I'll use general-def from general.el, you can still use emacs built-in functions to achieve these.

If I use C-<escape> as a "bridge", then I may do these to bind C-<escape> C-j to org-next-visible-heading and C-<escape> C-k for the other.

(general-def
    :keymaps '(org-mode-map)
    "C-<escape>" 'my/org-cmd
    )
(general-def
    :prefix-command 'my/org-cmd
    :prefix-map 'my/org-map
    "C-j" 'org-next-visible-heading
    "C-k" 'org-previous-visible-heading
    )

Then in meow:

(meow-normal-define-key
    '("C-j" . "C-<escape> C-j")
    '("C-k" . "C-<escape> C-k")
  ...
)

This way I can press C-j to trigger org-next-visible-heading.
And one day if you do not use meow, your prefix command my/org-cmd is still here for you to use.
