If you use Vim you should know by now how important it is to use modifier key. In old days, the escape key was in the place of TAB so it wasn’t any problem. But modern day keyboards have CAPS LOCK in the place of old ESC. Let’s change it.
~/.xinitrcand add this solitary line
setxkbmap -option caps:escape &
~/.xmodmapand add these:
remove Lock = Caps_Lock keysym Caps_Lock = Escape
xmodmap ~/.xmodmapto autostart xmodmap on system startup.
While we’re at it, let’s check how long have you had your Arch Linux installed ,
head -n 1 /var/log/pacman.log will output the exact date your pacman (hence Arch) was installed.
