You're right, of course. I had intended a better description for a later
version, but seeing as you've asked ;-} here's a quick summary. I'll add
these into the README file. There's also the main documentation online at:

http://www.speakeasy.org/~msaye/tk/listbox/
http://www.speakeasy.org/~msaye/tk/listbox/doc/en/listbox.html
http://www.speakeasy.org/~msaye/tk/listbox/doc/en/listbox.txt

Feature Summary
---------------

<Control-a> selects all listbox items

<Shift-KeyPress-Up> and <Shift-KeyPress-Down> move selected items up/down.

<Return> generates a <<ListboxActivate>> event.

<Double-1> generates a <<ListboxActivate>> event.

Clicking inside the listbox, but outside of any listbox items, clears
the selection.

You can sort the listbox while maintaining the selection and active item.

There is a chronological selection, so you can see which order items
were selected (i.e. when you get a <<ListboxSelect>> event, you can get
the last index from the selection to find out which item was actually
selected/deselected.

You can export the listbox selection without the selection being cleared
when making a selection in another widget (see http://wiki.tcl.tk/9597)

You can replace listbox items with a specified string (either all
selected items, or by specifying indices).

You can remove/delete listbox items (either all selected items, or by
specifying indices).

You can set the listbox's maximum height.

The package does *not* modify Listbox class bindings, so will not affect
standard listboxes. It creates the new bindtag eListbox (for extended
listbox), which imports all Listbox bindings, and thus overrides some of
them.
