alt + arrowkeys (left n right) in instrument panel used to skip like a PAGE of instruments in older versions. In latest 2.8b2 only ALT+RIGHT ARROW takes you pages down. while ALT+LEFT ARROW only takes you to the top what’s shown in the last page. It doesn’t go any further up. I wanna use this to skip instruments fast, don’t remove this functionality.
Actually after some testing… ALT+LEFT arrow actually skips a page down instead of up. So there you have the bug 
Probably easy as peacy to fix.
Already reported and should be fixed for B3.

And this should of been in the Beta forum.
Hmmm yes you are right… sorry.
