// MAIN SELECTOR WINDOW
// --------------------
// KEY CONTROLS
//   tab: toggle search box focus (FIXME: currently, only focusing works)
//   arrow left/right: if search box is not in focus, select previous(left) or next(right) category in "categories" combobox, wrap around when at either end.
//   arrow up/down: select prev/next entry. When already on top/bottom item, wrap to other end of the list.
//   enter: activate highlighted entry
// SEARCHING
//   The result list is sorted descending by 'score'.
//   Syntax 'abcdef': searches fulltext (ingoring case) in: name, filename, description, author name/mail (in this order, with descending rank) and returns rank+string pos as score
//   Syntax 'AREA:abcdef': searches (ignoring case) in AREA: 'guid'(guid string), 'author' (name/email), 'wheels' (string "WHEELCOUNTxPROPWHEELCOUNT"), 'file' (filename); returns string pos as score
