The point was that I was trying to avoid activating and deactivating tracks every time I wanted to make an edit using the COMMAND+K shortcut…it kind of defeats the purpose of using a shortcut key. I mostly edit music videos and there will be upwards of 75 tracks that I’ll be cutting between. It becomes time consuming to be constantly clicking tracks on and off.
That being said, I somehow solved my own problem. I had to reinstall Premiere, and when I did, apparently some setting got restored…I can now make shortcut edits by simply selecting the region and clicking COMMAND+K. However, if the region is not highlighted, the shortcut will make an edit to any track that is currently active (including audio).
Hope this helps anybody else who was having the same problem!
