A minor correction: Contrary to Yucca's statement, there are, in fact, commercially available physical keyboards with the recommended added engravings. I am using at my home office a wireless one hooked to my laptop.

Functionally, it is called “Modifier: stroke”, and it placed in AltGr position in the E00 key (which has the engraving “§”, so in that sense the assignment is arbitrary) and duplicated in AltGr position in the C09 key, for “L”. This may sound odd, but the background is that E00 is little used, but on the other hand it does not exist on many portable device keyboards, so duplication was needed. The choice of “L” reflects the practical situation that on Finnish keyboard, the modifier is most often needed for the letter Ł (ł) in Polish names; for “ø”, we can use AltGr Ö (since we see “ø” more or less as a counterpart to “ö”).

The recommended engraving for E00 is that in the right-hand position, where engravings for AltGr symbols and functions are placed, is letter “đ” so that the “d” part is gray. So far, there are no physical keyboards that contain the recommended added engravings. That is, we use old keyboards (usually Finnish-Swedish keyboards), so people just have to learn the new assignments and remember them.
