[Qemu-devel] [PATCH] Reduce curses escdelay from 1s to 0.2s

[Samuel Thibault <samuel.thibault@gnu.org>]

By default, curses will only report single ESC key event after 1s delay,
since ESC is also used for keypad escape sequences. This however makes users
believe that ESC is not working. Reducing to 0.2s provides good enough user
experience, while still allowing 200ms for keypad sequences to get in, which
should be more than enough.
