Dear Sir Ivan, it's an honor 🙂
What I meant is to use "Ripple Trim Previous Edit To Playhead", which is by default the Q keyboard shortcut in Premiere, but for it to function only on one track and to the selected clip.
This default option is described here: "Q & W Shortcuts Trim Clips Quickly" https://www.youtube.com/watch?v=RL4Gb1EKriI
But this works only when you are reviewing clips put on only one track and having all the other track empty. What I would like is for it to work on only one track, not to affect all the other tracks where I have other clips.
The commands Trim In/Out Point to Playhead while very useful, I believe they behave a bit differently – they do not delete the empty space created after executing the command.
