Hi,

When using describe-function, have shift-tab to move cursor to the  
previous link in the text.

for example, do C-h f search-forward. Then, press tab a few times,  
then it'd be nice to press shift-tab to move back.

Thanks.

Emacs already does this.

[In a Help buffer]: C-h k S-<tab>

  <backtab> (translated from <S-iso-lefttab>) runs the command
  backward-button, which is an interactive compiled Lisp function in
  `button.el'.

  It is bound to <backtab>, M-TAB, <menu-bar> <Help-Mode> <Move to
  Previous Button>.

  (backward-button n &optional wrap display-message)

  Move to the nth previous button, or nth next button if n is negative.
  If n is 0, move to the start of any button at point.
  If wrap is non-nil, moving past either end of the buffer continues from
  the other end.
  If display-message is non-nil, the button's help-echo string is
  displayed.
  Any button with a non-nil `skip' property is skipped over.
  Returns the button found.

O, thanks. I didn't know that.

on mac, win, linux, the usual key set for meta is such that meta-tab  
is taken by the OS system wide to switch between apps.
see http://en.wikipedia.org/wiki/Table_of_keyboard_shortcuts

So, i'm thinking Shift-tab as the default shortcut would be great.

just some thoughts.

Thanks.

Good suggestion; actually Emacs already does this.  Do you run it on a
terminal that does not distinguish tab from shift-tab?
