Is there a tactic to split multiple conjuncts in a goal into subgoals? If I have the goal P /\ Q /\ R, I want to split it to produce three subgoals at once: P, Q, and R I can't seem to find any info on this.
You can chain tactics. Split twice to split into 3.
(* Goal P /\ Q /\ R *)
split; [|split].
(* 3 subgoals:
- P
- Q
- R
*)
