Ten Bizarre Key Combinations in Word 2013
Ctrl+F12 — Open
The good news about Ctrl+F12 is that it’s not redundant to the Ctrl+O command. Ctrl+O is supposed to be the Open command, summoning the Open dialog box. In Word 2013, Ctrl+O displays the Open screen — it’s not the same thing. Ctrl+F12, however, takes you directly to the Open dialog box.
