Photoshop :: How To Apply Many Transitions Efficiently

i edit lots of software video tutorials inside Photoshop CS6 and overlay the videos with lots of red circles and keyboard keys. All these overlays need a short fade-in and fade-out. How can i apply these fade-ins and fade-outs more efficiently?

- If have to drag every single fade-in and every single fade-out to every single object, these are two actions per object. I believe there is no keyboard command for this and also i cannot create my own keyboard command here.
 
- Often i *copy* an object with Ctrl-J which already *has* the fade-in and fade-out. But the newly *copied object* does *not* sport the fade-in and fade-out; so i have to apply those manually again.
 
Is there any way to speed up the procedure of applying transitions? (Bulk-apply transitions? Keyboard ways?)I already tried to activate the special time-frame keyboard commands. (applying transitions). What's more, with special time-frame keyboard commands active, the arrow keys get new tasks then; but i need the arrow keys for *regular* keyboard commands in connection with the move tool (to precisely move the overlay objects to their desired position).
 
If you know any *advanced* tutorials on video in Photoshop CS6 (written or video), i would be interested. I am very familiar with general Photoshop including general video there. I don't need any introduction.

I have also tried to do my tasks in Premiere Pro CS6, but found it a bit overwhelming and went back to edit the video tuts in Photoshop. Even though after some getting-used-to-it, Premiere might be better for me. I *do* have to import lots of smart-objects and vector-objects with transparency from Photoshop all the time, and Photoshop is my natural habitat.
