While having more than 30 coordinates, and around 20 of them are still accurate, i think it should have around 30 slots. Yes, /c6 is was too faster than using macro (too slow)/autoreplace (i'll say same time, "c-ny" for example) to write it. But alias will be better. As /c o-alpha or /c ny . As you won't need to write /showcoords to look for them.
