Saving Time in Designing
I used to animate graphics for those LED signs at certain popular fast-food chains. There would sometimes be a library of 80-120 short videos that needed to be resized or scaled down.
I figured out how to make a system macro that memorized some of my mouse clicks and keyboard strokes, and it automated a previously four-hour task into something where I could hit one button and start sketching out ideas for other projects. Credit: Reddit/KourteousKrome
