Emacs keybinding for switching tab via number

Question

In Emacs 27.1, using tabbar. Trying to switch to tabs using numbers. Editing ~/.emacs with following lines doesn't switch tabs using C-1. Produces C-u 1 and so on. What is missing here? Any other comfortable option?

(require 'tabbar)
(global-set-key (kbd "C-1") 'tab-bar-select-tab 1) ; move to 1st tab
(global-set-key (kbd "C-2") 'tab-bar-select-tab 2) ; move to 2nd tab

Answer 1

global-set-key doesn't take 3 arguments.

(global-set-key (kbd "C-1") (lambda () (interactive) (tab-bar-select-tab 1)))

Or better yet:

(defun move-to-first-tab ()
  "Move to first tab."
  (interactive)
  (tab-bar-select-tab 1))

(global-set-key (kbd "C-1") 'move-to-first-tab)
