F11 on certain models, if different, specify keyboard model.
On a US Dell keyboard, the key above the Enter key is for the backslash (\) and the pipe (|).
-----
More properly, "|" is a "vertical bar" or sometimes a "vertical slash", just a "bar" [with context or local usage to distinguish between other (e.g., horizontal bar, top bar, double bars) uses], or even a "stick". "Pipe" is a term borrowed from computing because it is the symbol used in, for example, most UNIX shell scripts (programs) to indicate that two processes are linked (or chained) together and the output (standard out, optional standard error) from the left side is fed (or transferred) (i.e., "piped") to the process on the right side as input (standard in). Some later DOS and MS Windows batch or command utilities adopted this usage. "|" is used as a symbol in other computer languages, symbolic logic, mathematics, etc., so you may hear other names derived from what the symbol represents.
The backslash is right above the enter key..The problem is if you're using a Korean font, it will be the Korean WON symbol...but essentially it is the same key. just change your font and you will see the dfiference.
The symbol above 8 on a keyboard is * (also called an asterisk).
@ It is the symbol above the number 2 on the QWERTY keyboard.
Use the Backslash key, just above the "return" key on the right side of the keyboard. The key will have two characters: | ("pipe") and \ ("backslash").
asterisk
~ tilde ` prime
The symbol above the 7 on the keyboard, "&", is an ampersand. It is used in place of the word "and".
If it is to the left of the 1 key it is called the tilde key
There is no symbol above the number 0 on my phone keyboards. So clearly, it is not a standard.
The symbol for Ampersand or and is "&." It is found above the numeral 6 on an Italian keyboard.
ampersand
That is an asterisk.
