Supplementing Millie's correct answer, I often like to use this version of the navigate event that I first saw in Internet-Janitor's Dex-Vex.
on navigate x do if !deck.locked send navigate[x] end end
With this version you can still use arrow keys in interact mode -- but only while the deck is unlocked. This can be useful while building and testing.
But when the deck is locked for publication the keyboard navigation is completely removed, exactly like in Millie's version.
