Let’s say you’re doing something important on your computer, and you have an absent minded moment, and do something you immediately regret. You changed some formatting, or you deleted something, or you moved an image a fraction of a pixel to the left and then your entire document rearranged itself. You’re not sure what happened, but now something is wrong and you have no idea how to fix it.
What do you do?
Curse? Feel your heart sink into your belly? Panic? Say terrible things to yourself??
STOP! Mistakes are how we learn, after all. This kind is almost always easy to fix, and it’s a lot easier if you keep calm.
If the error is something you’ve typed, or reformatted, or something like that, all you have to do is:
press Control+Z.
In almost any program or platform, this will undo your most recent change. Depending on the circumstance, you can often undo many changes (as long as you have not clicked “save” anywhere.)
In addition, cloud-based programs like Google Workspace usually keep all previous versions of documents, so you can read them or even revert back to them if you like them better.
