C-h c TAB says: "TAB runs the command indent-for-tab-command" in emacs -nw

I can say
  (global-set-key (kbd "TAB") 'vimpulse-abbrev-expand-before)
and that works.  But
  (vimpulse-imap (kbd "TAB") 'vimpulse-abbrev-expand-before)
throws an error:

C-h c C-v says "C-v runs the command cua-paste" although vimpulse.el
(which executed without errors) contains:

  (define-key viper-vi-basic-map "\C-v" 'vimpulse-visual-toggle-block)

Executing this line doesn't throw an error but also doesn't fix the problem.
