Well, yesterday, in a tutorial, I found a tip/trick I have been waiting for. And, because I am so generous, I thought I would share it with you here. It's pretty simple, but saves "clicky time."
When you are resizing a picture by dragging on the corner squares, simply hold down the Shift key at the same time, and the ratios of width to height will stay true. Up until this time I have been clicking on the lock button, which takes at least 5 more seconds. I know, I know, I am saving you so much time.
Also, another shift extravaganza of fun. When rotating an object using the corner square, press the shift key again, and it will help you rotate on specific angles (45,90,60,etc). I know, you love trying to line up a picture so it is hopefully completely straight, but if you are ever in a hurry, now you can do it without question.
I hope you enjoyed this super small tip/trick about Photoshop, but if you are like me, you may love every small thing that may save time, clicking, sanity, etc. Happy Tuesday!
