Control-Y
Control-Y is a common computer command. It is generated by holding Ctrl and pressing the Y key on most Computer Keyboards.
In most Windows applications this keyboard shortcut functions as Redo, reversing a previous Undo. In some programs such as Microsoft Office it repeats the previous action if it was something other than Undo.[1]
Apple Macintosh systems use ⇧ Shift+⌘ Command+Z for Redo.[2] In general a shortcut on Macintosh using ⌘ Command matches up with a shortcut on Windows using Ctrl, this is one of the most noticeable conflicts. Many programs (on all systems including Linux) support both Ctrl+Y and Ctrl+⇧ Shift+Z for Redo to resolve this conflict. But quite a few remain where only one or the other shortcut works.
Other uses
The OpenVMS operating system command-line uses Ctrl+Y as its "abort" character, stronger in effect than the ordinary Ctrl+C "interrupt" character.
Ctrl+Y deleted the current line in the WordStar word processor for CP/M and MS-DOS.[3] 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.[citation needed]
In the pico and nano text editors this shortcut scrolls one page up.[5][6]
In SAP GUI it enters block-select mode.[citation needed]
