I’ve just updated to the latest version of Audacity.
In the previous version that I was using, I could use shift + s to switch between selecting in just one track by default, and auto-selecting across all tracks whichever track I dragged my selection to cover. Incredibly handy for cutting out a column of audio. Probably my most-used keyboard shortcut with the possible exception of mute.
In the new version this option seems to have vanished. I can use ctrl + shift + k to take an existing selection in one track and extend it across all tracks. But there doesn’t seem to be a way to just do this by default whenever I make a selection.
Can anyone tell me if this function still exists?
ETA: I forgot that it also means when I paste in new audio, all other tracks are auto-shifted to the right. Again, very handy if I want to add audio in the middle of other audio.
