bug#16327: 24.3; Arrow keys not working in virtual terminal after key binding

[Yi Wang]

[-- Attachment #1: Type: text/plain, Size: 13907 bytes --]

In a virtual terminal (i.e. the terminal without X, the one after
pressing, say C-M-F1), if the following code is evaluated, arrow keys no
longer work correctly. The 4 arrow keys becomes ABCD.

(global-set-key (kbd "M-[") '(lambda ()   (interactive) (other-window -1) ))

Note:

(1) This bug is reproducible with emacs -nw --no-init
(2) Under a X-environment terminal, say konsole, there is no problem.

bug#16327: 24.3; Arrow keys not working in virtual terminal after key binding

[Stefan Monnier]

> (global-set-key (kbd "M-[") '(lambda ()   (interactive) (other-window -1) ))

Don't quote your lambdas, please!

As for your problem: (kbd "M-[") is the same as ESC [ which is
a sequence of bytes often used by the escape sequences of arrow
keys, so your binding will indeed conflict, tho it will depend on the
specific terminal emulator used.
