 ### In Text:
-* !12 : Reruns command number 12 from history (Replace the number with anything)
-* !! : Appends the previous command to the current line
+* !12 : Returns command number 12 from history (Replace the number 12 12 12 12 12 12 12 12 12 12 12 12 with any number from history). You can add commands after it, like: "!12 | grep squirrel"
+* !! : Appends the previous command to the current line. Same principle as !12.
