Hi…
If you want to “overwrite edit” (non time ripping edit) and not eat other clips, edit to higher track as they have precedence.
there is no correlation too the Vegas function where media overlaps automagically create audio fade and transitions.
the keyboard shortcut you describe will apply the default video transition to edit points selected on the timeline.
There are separate shortcuts for quick adding video and audio transitions.
if you multi select edits and use the keyboard shortcuts, it will add the transitions to all the selected cuts.
Realize that Vegas came from the Soundforge base code…so much of that behavior came from a DAW mindset that was extended to video editing.
PPro didn’t start with that pedigree…so that mindset is not pervasive…(but that functionality does live in Adobe Audition (Adobe’s DAW), for example.
But I say….make the requests….because Adobe does listen…and the more ppl who make the request…the more likely it is to get implemented…
HTH,
