In the pico and nano text editors this shortcut scrolls one page up. In vi and vim it scrolls the display up one line. In emacs it does a paste action (known as "yank").
In Borland IDEs it also deletes the current line. In the 1980s, many text editors and word processors mimicked the WordStar command set, making Ctrl+ Y a common synonym for "delete line." The OpenVMS operating system command-line uses Ctrl+ Y as its "abort" character, stronger in effect than the ordinary Ctrl+ C "interrupt" character.Ĭtrl+ Y deleted the current line in the WordStar word processor for CP/M and MS-DOS. But quite a few remain where only one or the other shortcut works. Many programs (on all systems including Linux) support both Ctrl+ Y and Ctrl+ ⇧ Shift+ Z for Redo to resolve this conflict. To use these shortcuts, you may have to change your Mac keyboard settings to change the shortcut for the key. This topic flags such shortcuts with an asterisk ( ). 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. Some Word for Mac keyboard shortcuts conflict with default macOS keyboard shortcuts. Īpple Macintosh systems use ⌘ Command+ ⇧ Shift+ Z for Redo. In some programs such as Microsoft Office it repeats the previous action if it was something other than Undo.
In most Windows applications this keyboard shortcut functions as Redo, reversing a previous Undo. It is generated by holding Ctrl and pressing the Y key on most computer keyboards.
