Re: " What is the purpose of the →↑→↓←↓→↑④歩 combo that's shown in the note at the last inventory tab?"

In the empty snowfield it's directions to the hidden robot factory/"ancient" advanced city.
Walk right from the start you hit a Scarecrow, walk north you hit a tree.
Keep following walking as far as you can in those directions until you hit trees. With the last walk right you'll hit another scarecrow. Take 4 steps north and hit Z to uncover the entrance.
The first section is available early, I did it once I got that page, but the robots are mean at low level, and "hard" targets. Lightning magic is key, along with skills that hurt armored targets. Bring plenty of mana restore for the shrine maiden and use her AoE lightning ability lots, and hope it stuns them.
You can get the rocket launcher for the gun girl from the first sections. After you get that, well, you can 1 shot most normal fights.
The second section is unlocked once you get the ID Swipe card after liberating your original home castle. It leads to a fight with the male antagonist unlocking ancient weapons of tentacle destruction, the "secret" boss of the game, if you go there instead of the enemy castle.
