I'm kinda new and I was typing up my blog post and accidently deleted a larg chunk of info. Is there an undo button anywhere?
@Imperator100: It may depend on the operating system and browser you're using. Try right-clicking within the text editor and see if there's an "Undo" option, I know there is in Chrome for Windows. Also, sometimes hitting unto will make everything in the editor vanish, don't worry, just hit undo a few more times and it should reappear.
Hope that helps. Ultimately, you just have to be careful.
