 Backspace composition no longer works with typical modern digital displays or typesetting systems It has to some degree been replaced with the combining diacritical marks mechanism of Unicode, though such characters do not work well with many fonts, and precomposed characters continue to be used.Some software like TeX or Microsoft Windows use the opposite method for diacritical marks, namely positioning the accent first, and then the base letter on its position.Although the term "backspace" is the traditional name of the key which deletes the character to the left of the cursor, the actual key may be labeled in a variety of ways, for example "delete", "Erase" (for example in One Laptop Per Child), or with a left pointing arrow.
