Hello Dylan,
There are two ways (I know of) to easily work on subgoals:
1) You use the >- symbol and not \\ or THEN as it only applies to the
first subgoal
2) You use THENL an give it a list of tactics, where the i-th element
the list is applied to subgoal i.
Personally, I would recommend
Hi Dylan,
from HOL/help/Docfiles/HTML/Tactical.NTH_GOAL.html
(or help "NTH_GOAL" ; )
Where tac1 and tac2 are tactics, tac1 THEN_LT NTH_GOAL n tac2
applies tac1 to a goal, and then applies tac2 to the n’th resulting subgoal.
Cheers,
Jeremy

When a goal is separated into multiple subgoals during a proof of the form

Where the last tactic is something like

Is there a way to specify that the next tactic should be applied to a specific
subgoal? In the proof I’m working on, it was
