OOo has several windows like "Style & Formatting" and Navigation window, which
provide several lists (tables, styles, headings, figures, etc).

Currently the user has to manually scroll in the available list of entries. 
This is a non-productive way of locating the right entry.

Instead, provide "type-ahead" to locate the desired entry quickly.

Note: I am not sure of the term-- Probably this feature is described as
"incremental search" or "predictive entry"

What I mean is, if I enter "h", the highlight should jump to an entry that
begins with "H". If I enter more letters quickly, Writer should try to match the
entire string and find a suitable entry. For example, when I type "he", the
highlight should jump to an entry that begins with "he" (say, "Heading1"), and
so on. 

(If the matching entry is not found, the highlight should stay on the current
entry).
