Question

Adobe Photoshop

Hello!
There are some simple photoshop questions.
1) If we click on the preview of the layer with the control key held down, then we do, select the layer?
2) Why are the values ​​and parameters of the previous layout you worked with always saved in the layer overlay options (layer styles), and are not reset to default values?
3) And one more question on "preserve opacity" in layer fill.
I clearly indicated all this in a short video question - https://yadi.sk/d/gr6isgqDgoJT6w
Thanks for the answers!

If you want to thoroughly master Photoshop, then simply repeating other people's work on videos on YouTube will not work. You need to sit down and go through the entire course from beginning to end. Understand the basics, and then you can already play with other people's methods.
I recommend Andrei Zhuravlev's courses “Adobe Photoshop. Basic level”, then “Adobe Photoshop. Advanced level "well, and all related. After them, you will learn to think the way Photoshop does. Courses are paid, but if you really want to ... You understand. I hope I don't get a hat, this is not advertising. I studied them myself.
PS ^ I looked, it seems that they already lie for free. It's been a long time, maybe school policy has changed...
