I found this snippet which is useful for doing a move/rename without having to duplicate lines, it should take a shorter number of keystrokes ```bash mv wobblysci{.jpg,.bak.jpg} ``` This essentially* expands to ```bash mv wobblysci.jpg wobblysci.bak.jpg ``` rather than having to tab complete the filename and delete/arrow around, tab completing once, appending the new name, and bracket wrapping works (or vise-versa).
