Agreed, and in fact the behavior with '-selectmode single'
is much like a listbox with '-selectmode browse' (selection
is linked to the focus item, etc.)  Likewise a ttk::treeview
with '-selectmode multiple' acts (mostly) like a core listbox
with '-selectmode extended'.

I used the keywords "single"/"multiple" because that seems more
intuitive than "browse"/"extended" (even though the behavior
is closer to what the core listbox calls the latter).
