This page is about the notation of key sequences in Emacs documentation and in Emacs itself (GUI, terminal-mode).
‘S-TAB’means Shift Tab)
A notation such as
‘C-M-x’ (or, equivalently,
‘M-C-x’) means press and hold both Control and Meta (Alt) keys while hitting the
Some keys are referred to as “function” keys or “pseudo” keys. This includes keys that are not among the keyboard function keys
‘F12’. It includes keys that might not be on your keyboard, but are on other keyboards. It even includes keys, such as `
<insert-file>’, that are not on any keyboard, anywhere. For one thing, Emacs treats menu bindings as key bindings: a menu item is implemented as a pseudo key.
Starting with release 21, the GnuEmacs maintainers decided to denote such keys by enclosing their names in angle brackets:
<...>. Examples: `
<delete>’ is the Delete key, `
<insert>’ is the Insert key, and `
<tab>’ is the Tab key (or rather it is sometimes, depending on your keyboard).
Modifier keys that are part of a key sequence that contains a pseudo key are sometimes written inside the angle brackets: `
<C-insert>’. And sometimes they are written outside: `
No. If you would like to do without the angle brackets, at least in most interactive contexts (i.e., not hard-coded, literal occurrences), you can do so. Just use library NaKeD (No Angles Key Descriptions).
