[Suggestion] Arrow keys or page up/down to scroll

[MegaMech]

It would be a nice feature, if page up/down or arrowkey left/right could switch which drop down a person is viewing. This would make the program more efficient due to requiring less clicks.
Sometimes there's like 300 "entry variants" or objects in the list. It takes a long time to manually click through all that. (obviously you can use down/up arrows but only when the button already has focus)

Also, sometimes CTRL+S types into a box rather than saving. This may be because CTRL+S felt like it didn't work the first time, so it's pressed again while the program already is saving. Perhaps change the cursor to the loading spinning cursor so the user has some feedback that the program is indeed in the process of saving.

Also, when you click the tag search button please make the textbox take focus so that users don't have to click on it.

Allowing highlighting of multiple tags with shift and ctrl and adding all of them to the extract list would be nice too.

Please make it possible to remove single items from the extract list.

Thanks for your hard work on this. Assembly works really well.
