Subject: [PATCH] #3945 deck list: Navigation keys (PageUp/Down, Home/End) 
 (#5103)

* #3945 deck list: Navigation keys (PageUp/Down, Home/End) interact with the deck list.

* make Home/End work normally when there is text in the search textbox

* fix debug build, explicit cast from int to Qt::Key enum
