The keymap of BibTeX mode contains

    (define-key km "\M-\t" 'bibtex-complete-string)
    (define-key km [(meta tab)] 'bibtex-complete-key)

So bibtex-complete-key can be called by typing M-tab whereas
bibtex-complete-string can be called by typing ESC-tab. This is
distinguished correctly by describe-bindings in the list of defined
keys. However, where-is says that bibtex-complete-string is bound to
M-tab. Is this a bug of where-is? 

What key sequence should be typed for calling bibtex-complete-string
if one is using a tty without a meta key? Or might it be a better
idea to change the above key bindings?

Thanks a lot,
