You can see what is going on using `C-h c TAB', which will show you how
Emacs understands what your Tab key sends. In all terminals I know, the
Tab key sends ^I (i.e. ASCII 0x09), so you have to use something like
"\C-i" for the event you want to bind (instead of [(tab)]).

No idea. `C-v' does the right thing for me both in the terminal and the
GUI.

Indeed, nothing there suggests `C-v' shouldn't work.
Could the problem be that something other than Emacs catches the C-v
event?
