딥러닝 🐍

요즘 emacs나 vi에디터를 많이 쓰면서 control키를 새끼 손가락으로 누르는 일이 많아졌다.

보통의 키보드에는 control키가 왼쪽 아래 존재하다 보니 새끼 손가락이 많이 무리가 간다.

옛날의 unix키보드처럼 배열을 바꿔서 사용해보려고 한다.

# 먼저 아래 파일을 Editor로 연다.
$ sudo vi /etc/default/keyboard

# XKBOPTIONS을 찾아 ctrl:nocaps를 써서 Caps Lock키를 추가적으로 Control키로 사용하도록 한다.
# 또는 ctrl:swapcaps를 써서 Caps Lock키와 Control키의 기능을 바꾼다.

XKBOPTIONS="ctrl:nocaps"

# 다음으로 변경된 내용이 반영되도록 아래 명령어를 실행한다.
$sudo dpkg-reconfigure keyboard-configuration
