How to create the ` symbol

Creating the ` symbol on a U.S. keyboard

To create a back quote using a U.S. keyboard, press `, which is located directly below the Esc key. This key is also used for typing the tilde ( ~ ) character if the Shift key is held while it is pressed.

Creating the ` symbol on a smartphone or tablet

To create a back quote on a smartphone or tablet locate the single quote in the numbers (123) or symbols (sym) section, and tap and hold the ’ symbol. As you continue to hold down on the ’ symbol, a menu containing the back quote appears. Drag your finger up to the back quote and let go to insert the symbol.

Doing the Alt code Alt+96 can also create a back quote.

How is a back quote used on a computer?

Below are a few examples of how and when the back quote is used.

  • When used as an accent, the grave accent indicates pitch, stress, or tone of a letter. How it’s used varies by the language.
  • In some programming languages, the backtick can be used for command substitution. For example, below is an example of Perl code that uses backticks to execute a system command and load the command output into an array.

@files = dir /b c:\windows\temp;

In the example above, the backtick substitutes the command output into the elements of the “@files” array. In this case, each element is the name of a file or directory in the c:\windows\temp directory listed by the dir command.

The single quote should be used in your writing instead of using the back quote. In other words, use a single quote instead of a back quote when writing the apostrophe in words like “don’t” and “I’m.”

  • In Unix and Linux shells, the backtick is used as an indication of what to evaluate (execute) first in a command. For example, in the following command, the “hope” variable is assigned the output of the date command. When this command is run, the date command is executed first, and then its output is assigned to “hope.”

hope=date

After entering the above command, running “echo $hope” echoes the value of the “hope” variable, which is the date and time when the original command was run.

  • When used in a comment, the back quote is sometimes used to emphasize code contained in the comment.
  • The back quote key is also used to access the console in programs and games like Quake.
