Use your keyboard to right-click on your Windows 8.1 computer if your mouse is broken or you don't want to use it for another reason. With the Mouse Keys feature, you can move the mouse and perform click actions using the numeric keypad on your keyboard. You can also use a keyboard shortcut to right-click in both Windows 7 and 8.1 computers.
Right-Click in Windows
Mouse over the upper-right corner of the screen, move the mouse toward the bottom of the screen and click "Search." Click "Settings," type "how your mouse works" into the search box and click the "Change how your mouse works" link. Check the "Turn on Mouse Keys" box and click "OK." Click the "8" key on the numeric keypad to move the mouse pointer up, the "2" key to move it down, the "6" key to move it to the right and "4" to move it to the left. Click "-" to select the right mouse button and then press "5" to right-click. To left-click, press "/" and press "5."
Another way to right-click in Windows 7 or 8 is to use a keyboard shortcut. Press "Shift-F10" after you select an item to right-click it. Use "Alt-Tab" to switch between windows and the "Alt" key to select the menu bar in most Windows programs. Use the arrow keys to select different items.
