Does anyone else do this?

I don;t know of anyone in real life who does this, but I find it a lot easier to keep track of what I'm thinking of if I draw it out in the air in front of me, and do things like select and move objects (letters, characters, images). I don;t actually see anything, but it'ds a lot easier to envision and keep track of a particular subject that I'm trying to think through. It even helps with math if I type numbers into an imaginary calculator or numberpad, and for some reason, I can remember which number keys are where then, but not on an actual calculator or keypad. (And I don;t actually envision a computer screen, I just sort of think the different marks and characters in place, where I draw them, sometimes having to "erase" if I make a mistake or have a better idea aboutr how something can be done. There is no undo on my invisible computer.)

So, does anyone else do this? Go ahead and share any things you do to help keep track of your immediate thoughts.
