In the 1980s, many text editors and word processors mimicked the WordStar command set, making Ctrl+Y a common synonym for "delete line." In Borland IDEs it also deletes the current line. In emacs it does a paste action (known as "yank"). [4] Emacs uses Ctrl+/ for Undo and Redo. In vi and vim it scrolls the display up one line. [5]
[5] [6] [7] A line comment ends at the end of the text line. In modern languages, a line comment starts with a delimiter but some older languages designate a column at which subsequent text is considered comment.

vi (pronounced as distinct letters, / ˌ v iː ˈ aɪ / ⓘ) [1] is a screen-oriented text editor originally created for the Unix operating system. The portable subset of the behavior of vi and programs based on it, and the ex editor language supported within these programs, is described by (and thus standardized by) the Single Unix Specification and POSIX.
A line command is a string that the user types into a line number field and that the editor recognizes as a command operating on that specific line or block of lines, e.g., LC to translate a line to lower case, ))3 to shift a block right three columns. Some editors also support line macros, also known as prefix macros or sequence macros.
For example, . is a very general pattern, [a-z] (match all lower case letters from 'a' to 'z') is less general and b is a precise pattern (matches just 'b'). The metacharacter syntax is designed specifically to represent prescribed targets in a concise and flexible way to direct the automation of text processing of a variety of input data, in a ...
