There are two ways to send meta modifiers (ESC) depending on the
terminal emulator and its setting. One is to first press the Escape
key and then press 1 or 2. Another is to press 1 or 2 with the Meta
key being pressed. I use the latter, and in that case, it is intuitive
to input multiple-digit numbers with the Meta key kept to be pressed.

Ah, OK. You're right. Thank you for pointing it out. I'll modify it.
