A control character ("CAN", "Cancel", U+0018, or ^X) used to indicate that the data with which it is associated are in error or are to be disregarded. Exact meaning can depend on protocol. For example: In some journalistic text transmission formats, it signifies that the preceding word should be deleted; it is sometimes called "Kill Word" ("KW") in this context.[1] In some Videotex formats, it stops any running macros.[2][3] In others, it clears the current line after the cursor position (compare EL).[4] A control character ("CCH", "Cancel Character", U+0094, or ESC T) used to erase the previous character.
