Type: boolean
Default: no
If set, forces Mutt to interpret keystrokes with the high bit (bit 8) set as if the user had pressed the ESC key and whatever key remains after having the high bit removed. For example, if the key pressed has an ASCII value of 0xf4, then this is treated as if the user had pressed ESC then ``x''. This is because the result of removing the high bit from ``0xf4'' is ``0x74'', which is the ASCII character ``x''.
