Keyboard Shortcuts
Copy only active window to clipboard Normally, the Print Screen key copies the entire display (or two displays if you got them), ALT + Print Screen only copies the currently active window to the clipboard. Whether taking a screenshot to diagnose a problem, or just because you want to show something to a friend, this will come in handy.
Fix those little mistakes Did you know you can undo almost any action? CTRL + Z is the ultimate hot key, and for sure you knew about it already, however note that undo doesn’t just apply to typing. If you accidentally delete or move a file, you can hit CTRL + Z to bring it right back to where it was. In Chrome and Firefox you can also undo closing a tab using CTRL + SHIFT + T.
Cycle through open windows Pressing ALT+TAB allows you to cycle through currently open windows. This makes switching back and forth between running processes quick and painless. If you want a more stylish method of cycling through open programs, Windows + TAB will do the job for you.
Close the current program Typing ALT + F4 will close the program that is running. This is useful as it saves you time mousing over the "X" and clicking. People will often use this as a joke, telling you to press ALT + F4 to fix a problem. Don’t fall for it unless you want to close what you are doing.
Minimize all windows Sometimes you have a bunch of stuff running, and you want it all to go away so you can get to the desktop. Simply pressing Windows + D will minimize everything you have up, which will save you some time pressing the minimize button for each window. It should be noted that Windows + M offers similar functionality, but there is no undoing, so Windows + D is the more favourable approach.
Open the task manager directly If you want to bypass the interrupt that happens when pressing CTRL + F1 and jump right to the task manager, typing CTRL + F3 launches it directly.
Close the current window/tab Sick of moving all the way to that X button? Press CTRL + W and the current window will close. (Don’t do it now, or you will miss the rest of the tricks!)
