Pivot point is binded to the 3D cursor, scale with G only works with Ctrl I'm a moron, I know. This is my first real project in Blender I have a goal, and I'm walking through it step by step I'm fighting with Blender, my old crappy pc, I find out not just how to do it, but how to make it with a final render before the end of the epidemic.. and time to time, accidentally I push a combination of keys, and kill the whole software. Pls help, as google doesn't. Now:

The pivo point of every object is the 3d cursor (when I rotate, for example) - nothing is locked on the 3D cursor part of view panel.
Moving with G, only works if I push Ctrl when I'm moving my mouse, after G.

I just want to go back to normal, thanks..
I pushed shift + tab (shortkey of the button with magnet icon) accidentally
