Found it; the package was
objed! As quoted from the Github README:
A global minor-mode to navigate and edit text objects. Objed also enables modal editing and composition of commands. It combines ideas of versor-mode and other Editors like Vim or Kakoune and tries to align them with regular Emacs conventions.
