well at least I remember some tools and can google them, but I had a big disappointment when opened Blender after 2-3 years without it. All shortcuts (except 1,2,3,4) are forgotten

I weirdly had the opposite experience with Blender, didn’t open it for months once and the muscle memory kicked in when I came back to it. So much so that I was like “I can’t remember what this shortcut key was” but my body would know if I recreated the scenario for it lol.
