SA while back we asked you all to tell us which keyboard shortcuts you found most useful—we wanted to know about keystrokes that went above and beyond the basics. Here's the best of what you had to say, culled from some 200 responses. Are you ready to get your motherfraking optimize on?
From your desktop...
Of all the tips you gave us, some of our favorites are not necessarily well-known ways to get your computer into (or out of) an idle or locked state quickly by using a shortcut to bypass menus.
Windows+L: Lock your computer (Windows) — Thanks, Jimstoic
Opt+Cmd+Eject: Puts your computer to sleep (Mac) — Thanks, PrestigeWorldwide
Ctrl+Opt+Cmd+Eject: Hard shutdown without prompt (Mac) — Thanks, CRUMBshot
Ctrl+Shift+Eject: Turn off your monitor without going to sleep (Mac) — Thanks, Zack Pyle
Ctrl+Shift+Esc: Bypass Ctrl+Alt+Del and go straight to the Task Manager (Windows) — Thanks, SQLGuru
Getting rid of stuff is sometimes the most productive thing you can do.
Ctrl/Opt+Backspace: Erase whole words (Windows/Mac) - Thanks, Nick Berkowitz
Shift+Del: Permanently delete a file by skipping the Recycle Bin (Windows) —Thanks, atatassault47
Navigate your text...
No more jabbing at your keyboard endlessly to move back and forward. Be the Usain Bolt of the text box.
Ctrl/Opt+L/R Arrow: Jump forwards or backwards by entire words (Windows/Mac) — Thanks, Sketcher 0204
Ctrl/Cmd+L/R Arrow: Jump to the beginning or end of a line (Windows/Mac) — Thanks, brunski82
Ctrl/Cmd+L: Select the address bar — Thanks, MylarShoe
Ctrl/Cmd+Shift+T: Reopen the tab that you accidentally (and stupidly) just closed (Windows/Mac)—Thanks, DeadlyFatalls
Ctrl/Alt+Down arrow: Scroll down just a little bit — Thanks, nobody
Personally, I use this at least twenty times a day. A personal favorite.
Cmd+Shift+4: Pull up crosshairs for a selection screenshot — Thanks, Jservalli
Cmd+Shift+3: Capture a screenshot of your entire screen.
Holy crap how many displays do you have?
I never thought this would be a problem but user thisisharderthani thought clearly needs this one:
Windows+P: Change how many connected screens or projectors you want to use.
Make Office useful...
In Microsoft Office, user Chris Straughn likes:
Ctrl+Shift+K: To make "small capitals" (Windows)
Writing my dissertation in linguistics would have been so much more painful without this, as we use small caps a lot in our morphological glosses.
For Microsoft Office shortcuts that will probably be more useful to you, check out this nice PDF listing.
Obvious, maybe, but this Photoshop tip blew my mind...
Ctrl/Cmd+Alt/Opt+Z: Successive undos in Photoshop (Windows/Mac) — Thanks, candytaco
Why is this so crazy? In Photoshop, the old Ctrl/Cmd+Z toggles back and forth between your last step making it easy to compare the results of an option on your project. But add "alt" to the whole equation and you can keep going back in time forever and ever.
Now, I polled my colleagues and it turns out that I'm a total idiot for using Photoshop as long as I have without knowing this. But that's the beauty of shortcuts; just when you think you've learned them all, another one pops up that you'd somehow managed to overlook.
A few more resources...
Those are just a few of the shortcuts out there; if you want a more universal listing for Macs, check out Dan Rodney's neatly categorized collection. Microsoft, meanwhile, has a nice listing of shortcuts for Windows.
