>> Is it possible Speed Keys (Refer Org Manual - Sec. 15.3) for Babel
>> blocks?

Attached patch extends the speed key functionality.

Usage notes:

After applying the patch, use variant-1 or variant-2 to enable speed
keys within a babel block.

variant-1:

  (defun org-babel-speed-command-hook (keys)
    (when (org-babel-where-is-src-block-head)
      (cdr (assoc keys org-babel-key-bindings))))

variant-2:

  (defun org-babel-speed-command-hook (keys)
    (when (and (bolp) (looking-at org-babel-src-block-regexp))
      (cdr (assoc keys org-babel-key-bindings))))

  (add-hook 'org-speed-command-hook 'org-babel-speed-command-hook 'append)


Use this hook with caution.

  (defun org-speed-command-catch-all-hook (keys)
    'ignore)

  (add-hook 'org-speed-command-hook 'org-babel-speed-command-hook 'append)
