How to Type an Underscore
How you type an underscore depends on the device you're using. On computers, you use a key combination; on mobile devices, it's on the onscreen keyboard.
Things You'll Need
- QWERTY keyboard
- Mobile device
Typing an underscore is the same for a Windows or a Mac computer. On most standard keyboard layouts, the underscore shares a key with the hyphen character. Type it by pressing the Shift and H**yphen** keys. On standard U.S. keyboards, the hyphen key is located on the top row, to the right of the zero key. Onscreen keyboards for mobile devices vary; mobile devices have dozens of keyboards to choose from as downloadable apps. Most, however, follow a standard layout.
The standard to underline text used to be Ctrl-U. However, this shortcut is growing obsolete. Instead, highlight the text to be underlined and then right-click on the text, which often produces a menu with formatting options, including Underline. Alternatively, check the application's menus for a Format menu, which usually contains an underline option.
When choosing a username or secure password, use an underscore to increase the security of the password or add an underscore to an unavailable username to tweak it to one that is available.
On Mobile Devices
iOS (iPhone, iPad, iPod Touch)
Step 1Tap the 123 button. On the iPad, the button reads .?123 instead.
Step 2Tap the #+= button.
Step 4Tap the Underscore button. From here, you can tap either 123 to return to the numbers keys or ABC to return to the alphabetic keyboard.
On mobile on-screen keyboards, the underscore key is not immediately visible, so it takes multiple taps every time you want to type an underscore.
Step 1Tap the ?123 button.
