Yes, screenshot things.

But also export your config because you will inevitably forget to screenshot a thing or seven and you can poke around the config export for that port number or IP address.

Worst case scenario, you can spin up a VM of pfsense quickly and reimport the config if you have to.

I have off-box backups of my configs. Thanks for the VM idea; sometimes I forget to use VMs to do things "embedded" devices usually do for me; switches, routers, etc!

There's going to be a point soon where I have two fiber providers (and thus two WAN links) for a little while, I'll try move the existing pfSense off of my Protectli box to a VM, keep everything up for the family while I configure OPNSense on the Protectli, then if I do it right, I can move everything over with minimal reconfiguration.
