Emacs: Key Notation <return> vs RET
"<return>" vs "RET"
"<return>" is the Return key while emacs runs in a graphical user interface.
"RET" is the Return key while emacs runs in a terminal.
"RET" is also equivalent to
"C-m" (Ctrl+m). [see Emacs Key Syntax Explained]
if you define:
(global-set-key (kbd "<return>") 'backward-char)
and run emacs in terminal, your keybinding will have no effect.
you need to use:
(global-set-key (kbd "RET") 'backward-char)
But the problem is, by binding
(kbd "RET"), you are also binding
(kbd "C-m"), regardless you run emacs in terminal or GUI.
"<tab>" vs "TAB"
Same situation for
"<tab>"is the notation for Tab key when emacs is run in graphical user interface. If you define a key with
<tab>, it won't have effect in terminal.
"TAB"is the notation for Tab key when emacs is run in terminal.
"TAB"is also equivalent to
"C-i", in both graphical user interface and terminal. If you define key by
"TAB", it also defines
"C-i"(and vice versa), in both graphical user interface and terminal.
"ESC" is the same as
