In ocean course macro session at 13min 05 instructor said insert keyframe. If i do right click i don't have the option to insert a key frame. I use blender 3.6. It can be very useful to precise which version of blender is use for the course and this for each course.
Thank you :) For cycles what i nee to choose between this 4 render devices? 
That depends on your hardware, especially the GPU you use.
CUDA and OPTIX are for NVidia cards, with Optix requiring more recent chipsets, but I had it running on a GTX 970. I believe the 960 was the cutoff. Optix is also a lot faster in rendering, so if your hardware supports it, that's what I would use.
HIP is what you would use if you own an AMD card and I believe oneAPI is for the new Intel Arc cards.
Whichever you select make sure to check the mark on your GPU that shows up.
