It is called the pipe key
To change a lowercase "e" to a backslash, you can use the shift key and the backslash key on your keyboard. Simply press and hold the shift key, then press the backslash key to type a backslash character ().

Electronic Signature
The bar symbol on the keyboard is called the "vertical bar" or "pipe." It is represented by the character "|" and is typically found on the same key as the backslash (), often requiring the Shift key to be pressed. This symbol is commonly used in programming, mathematics, and as a delimiter in various applications.
Follow the backslash with another backslash: System.out.println("\\ " \"); will display \ " \ on the screen.
They are called forward slashes or just slashes for short. You can recognize that this is true when you realize that before computer keyboards, typewriters and typography in general had no such thing as the "backslash". (At least, not commonly.) The only "slash" was the "forward slash". (Think and-slash-or for and/or. When have you ever seen the backslash, "\", in literature? And have you ever noticed that the question mark/forward slash key practically always sits in the same location on all QWERTY keyboards, while the backslash is often in different locations on different QWERTY keyboards? It's not even always paired with the vertical bar.)
The proper name for a 'backslash' in print is a 'reverse solidus'.
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").
I think the backslash is right underneath the question mark on any computer.
