Favorite and lesser known shortcuts of your favorite programs
Everyone knows control + z. Everyone knows control + c and then control + v. But this a discussion dedicated to shortcuts that you cannot live without, but are not commonly used by many people know. I'll start off with one of my favorite shortcuts.
In firefox, this well reopen the tab you has just closed. I really have no idea how I even managed to use firefox without this shortcut. Since I go on tangents all the time during my browsing, I'll often close many of my 30+ tabs that are open and accidentally close what I was researching 20 minutes ago that I had forgotten. Since I hold down ctrl + w(another favorite) to close all the tabs quickly, closing a tab accidentally is a common occurrence. My left hand is always poised on my keyboard, ready to enact whatever shortcut it requires.
