Ctrl + Z

''Ctrl-Z > Ctrl-W. Fight me.''

Pressing the Ctrl (control) and Z keys at the same time will undo text you recently typed, bring back text you highlighted and then deleted using Delete or Backspace, and, in Google Chrome, will send you back a page if you aren't editing text or doing something else that would make Ctrl + Z perform a different action. In Windows' Notepad, doing it twice will undo the undo you just did. ''Holding it down will rapidly undo and undo the undo and undo that and so on... how fun...''

In UnTrash form (also known as the worst form), Ctrl + Z refers to when something is done then almost immediately or abruptly undone, like having someone's birth be undone with them suddenly falling out of existence. It also refers to moments when something or someone suddenly stops existing, like when a city is bulldozed into oblivion by a Nuclear Explosion. Oftentimes, when something is Ctrl + Z'd, it's Too Late To Save it and it's Gone Forever.
