Quando executo emacs -nw fora de screen , posso usar as teclas Shift + seta para selecionar o texto. Mas dentro de screen , quando pressiono Shift + para baixo, vejo: M-[ 1 ; 2 b is undefined . Mesmo com Ctrl + space, que diz Mark activated , não consigo usar Ctrl + n para selecionar uma região. Tudo isso funciona bem fora de screen .
Eu tenho essas variáveis de ambiente relacionadas dentro da tela:
$ screen --version
Screen version 4.05.00 (GNU) 10-Dec-16
$ emacs --version
GNU Emacs 25.1.1
Além disso, dentro do *scratch* , quando pressiono a tecla Ctrl + q, vejo: ^@ , independente de qual tecla de seta eu pressionar.
Alguma ideia de como diagnosticar / corrigir o problema?
Ler man emacs25 :
-nw, --no-window-system
Tell Emacs not to create a graphical frame. If you use
this switch when invoking Emacs from an xterm(1) window,
display is done in that window.
E, em screen , inicie o emacs com emacs --no-window-system
