DHTML Style Guide Listbox Proposal

Proposed by Aaron

1.	When a list is tabbed to, select the first item if nothing else
is already selected 
	      [This may be controversial, some people like to just focus
the first item, and then have the first space or down arrow cause
selection to happen.] 
2.	Up/down arrow key navigation. Shift+up and shift+down move and
extend the selection. 
3.	Typing letter or several letters to navigate (same letter goes
to each item starting with that, different letters go to first item
starting with that entire string). 
4.	Multiple selection is possible with Ctrl+arrow to move focus
without selecting, then space to select item, shift+space to select to
current point or control+space to toggle selection of current item.
However, in general users don't remember these keys and a multi select
listbox is really better done as a list of checkboxes. 
5.	Shift+F10 or context menu key to bring up context menu for
current item. On Mac OS X, ctrl+space is used to bring up the context
menu. 
6.	Space bar toggles checkboxes, if the list item is checkable 
7.	Show a lighter highlight color for the selection when the list
is not focused
