Hi Oldcat,

of course you are aware that some browsers already provide part of the functionality you describe: You click once on the pop-up with the author names, so the pop-up stays open and then you just start typing on the keyboard and the pop-up highlights entries which begin with the letters you type. Hitting ENTER selects what is highlighted in the popup. In Firefox this works, although I do not know if this works when you enter japanese characters. This will only pick up the first characters so if you look for "Osamu Tezuka" you can only find it by typing "Osam.." not by typing "Tezu…"

Maybe you can do it this way until there is a full search functionality in BookX.

Best wishes,
P.
