feature: the undefine-key function to delete an existing key in a keymap.

[sakurawald]

I have the folloing bindings:

(defun define-paired-commands ()
  (define-key lem-vi-mode:*normal-keymap* "[ b" 'previous-buffer)
  (define-key lem-vi-mode:*normal-keymap* "] b" 'next-buffer)

  (define-key lem-vi-mode:*normal-keymap* "[ w" 'previous-window)
  (define-key lem-vi-mode:*normal-keymap* "] w" 'next-window)

  (define-key lem-vi-mode:*normal-keymap* "[ t" 'lem/frame-multiplexer::frame-multiplexer-prev)
  (define-key lem-vi-mode:*normal-keymap* "] t" 'lem/frame-multiplexer::frame-multiplexer-next)

  (define-key lem-vi-mode:*normal-keymap* "[ s" 'backward-sexp)
  (define-key lem-vi-mode:*normal-keymap* "] s" 'forward-sexp)

  (define-key lem-vi-mode:*normal-keymap* "[ l" 'up-list)
  (define-key lem-vi-mode:*normal-keymap* "] l" 'down-list)

  (define-key lem-vi-mode:*normal-keymap* "[ f" 'lem/language-mode::beginning-of-defun)
  (define-key lem-vi-mode:*normal-keymap* "] f" 'lem/language-mode::end-of-defun)
  
  (define-key lem-vi-mode:*normal-keymap* "[ i" 'lem-vi-mode/commands::vi-search-backward-symbol-at-point)
  (define-key lem-vi-mode:*normal-keymap* "] i" 'lem-vi-mode/commands::vi-search-forward-symbol-at-point)
  )

The paredit mode will override the vi-mode bindings starts with [ and ]

  (lem-paredit-mode:paredit-mode t)

I would like to un-define the bindings that defined by paredit mode. Is there an easy way to do this ?

undefine-key is not yet implemented.
could you use override its commands with define-key?

undefine-key is not yet implemented. could you use override its commands with define-key?

It seems like the paredit defines the [ and ] keys in paredit-mode-keymap, it is conflict with vi-normal keymap and vi-insert keymap.

I don't know how to override this.

It would be good if there is a way to delete a key in a keymap

I think i can just comment out these lines, and compile a custom version for myself.
