@Adám what do you mean by at each level of depth? That X can indicate nested indexes?

@Uriel Yes, exactly. ((2 1)1 2)⊃Y means pick element at position [2;1], then from that, pick the element at position [1], then from that, pick the element at position [2].

So it is equivalent to ⊃(⊃(⊃Y[2;1])[1])[2].

@KritixiLithos (⊢≡⌽)'aeiou'∊⍨⊃∩/819⌶⍞⎕A for this.

Nice use of the ∩/

@KritixiLithos Thanks. It makes it possible to use 819⌶ on the nested array ⍞⎕A which doesn't need any spaces. Definitely worth the 1-byte slash.

@MartinEnder I've made a utility to generate such maps from a raw .klc file. Is this what you wanted? Would you like listings of dead key combos too?

I'll try that later this week, thanks. Listings for the dead keys sound useful.

@MartinEnder Hm, I just tried running it on TIO. I forgot that I used yet another feature (number 4…) of 16.0. I'll let you know if I manage to backport it to 15, and I'll try working dead key combos in.

@MartinEnder Woohoo!
