Table of keyboard shortcuts

In computing, a keyboard shortcut is a sequence or combination of keystrokes on a computer keyboard which invokes commands in software.

Some keyboard shortcuts require the user to press a single key or a sequence of keys one after the other. Other keyboard shortcuts require pressing and holding several keys simultaneously (indicated in the tables below by this sign: +). Keyboard shortcuts may depend on the keyboard layout (localization).

Keyboard shortcuts are a common aspect of most modern operating systems and associated software applications. Their use is pervasive enough that some users consider them an essential element of their routine interactions with a computer. Whether used as a matter of personal preference or for adaptive technology, the pervasiveness of common conventions enables the comparison of keyboard shortcuts across different systems. The following sections detail some of these comparisons in widely used operating systems.

A note regarding KDE's shortcuts is that they can be changed and the below list contains the defaults. Some of the combinations are not true for localized versions of operating systems. For example, in a non-English version of Windows, the Edit menu is not always bound to the "E" shortcut. Furthermore, many shortcuts (such as CTRL-Z, ALT-E, etc.) are just common conventions and are not handled by the operating system. Whether such commands are implemented (or not) depends on how an actual application program (such as an editor) is written. Not all applications follow (all of) these conventions.
