using Tab is probably worst, because every mode vie for that key.
in just about all modes, tab does indentation.
ysnippet also uses tabs.
org mode uses tabs.
in minibuffer and elsewhere, it's also used for completion.
not recommended to pile on such a key. Also, i noticed, tab key is not actually a good key. Need to take care of your pinkies.
