That's called cheating lol.Just FYI. I was interested in the first pic I opened from your post, ie. change versus modification time, and as I didn't know the actual answer (sure I could guess but why) I just entered a command into the terminal (`info stat`), used the search key (`/`) & bingo had my answer is <15 keystrokes and <5 seconds.
Even if I didn't know what manual page to look up; search tools exist (eg. `apropos` & more) so we can find the pages we cannot remember.
