scroll bar arrow in konsole / kde f27

i am a kde guy. i always install fedora kde spin when i can. recently, the arrows on the scroll bars in konsole has disappeared and makes it difficult to scroll back accurately. so here is the solution to get the scroll bar arrow back for kde konsole

(note: side effects may include scroll bar arrows appearing in other applications)

you want to open your "system settings" application. go to "application style". then click "configure" next to the "widget style" drop down. and enable the arrow(s)
