    Looks like !$ is a readline feature and $_ is a shell variable?

      Yes. $_ is documented here: https://www.gnu.org/savannah-checkouts/gnu/bash/manual/bash.html#Bash-Variables https://www.gnu.org/savannah-checkouts/gnu/bash/manual/bash.... And !$ is documented here: https://www.gnu.org/savannah-checkouts/gnu/bash/manual/bash.html#Word-Designators https://www.gnu.org/savannah-checkouts/gnu/bash/manual/bash....

      I don't think !$ is properly understood as a readline feature. It's a sh/bash abbreviation. !! -> last whole command !!:1 -> first argument of last command !!:$ -> last argument of last command !$ -> abbreviation for above
