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).
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").
@ It is the symbol above the number 2 on the QWERTY keyboard.
asterisk
~ tilde ` prime
The symbol above the 7 on the keyboard, "&", is an ampersand. It is used in place of the word "and".
The symbol above the 9 key on a standard keyboard is called the parentheses or "right parenthesis" symbol, represented as ")". In some contexts, it may also refer to the closing parenthesis used in mathematics and programming to denote the end of a grouped expression.
If it is to the left of the 1 key it is called the tilde key
To type a slash on a Microsoft Surface tablet, locate the forward slash key (/) on the on-screen keyboard or physical keyboard. If using the on-screen keyboard, you may need to switch to the numeric or symbols layout by tapping the "?123" key. For a backslash (), hold down the "Alt" key (if using a physical keyboard) and press the key located above the "Enter" key. If you're using the touch keyboard, you may find the backslash on the symbols page as well.
The symbol for Ampersand or and is "&." It is found above the numeral 6 on an Italian keyboard.
There is no symbol above the number 0 on my phone keyboards. So clearly, it is not a standard.
