the tab key and autoindenting

the tab key and autoindenting

[unimatrix01]

I recently was using emacs to edit some webpages and some projects I was 
working on at my work.  I came back later and I could not utilize the 
tab key in any mode and autoindentation did not work when I edited html 
or source files.  Is there any key combination or variable that I 
possibly changed that could cause emacs to prevent the tab key from 
working and the autoindentation to stop all together?  Thank you any help.

C-h k TAB says the following:

TAB runs the command lisp-indent-line
    which is an interactive compiled Lisp function in 
`emacs-lisp/lisp-mode'.
(lisp-indent-line &optional WHOLE-EXP)

Indent current line as Lisp code.
With argument, indent any additional lines of the same expression
rigidly along with this one.

so you probably issued "C-h k TAB" in a buffer which is in lisp-mode.

what if you do it in a buffer containing html-source ?

the meaning of the TAB key changes in general according to the mode of
the type of file you are editing.

you may change the meaning depending on the edit mode by calling
local-set-key from some hook provided by that mode.
