My Keyboard Shortcuts Setup as of May 2022

I made the so-called Hyper Key.

Then I configured a bunch of shortcuts to fly through my Mac. Remember ⌃⌥⇧ is the so-called Hyper Key that I made, which uses the Caps Lock key or 한/영 키 (Korean-English Key). That is, because, I never use the Caps Lock key (I use shift) and I click the right command key to type Korean and click the left command key to type English, inspired by the Japanese Apple keyboard's Kana (かな) and English Key (英数).
