Ke holoʻoe i ka kauoha i luna eʻikeʻoe i kahi mea hōʻino a hiki iāʻoe ke komo i kahi inoa inoa. Ke komo kokeʻoe i ka pinepine pinepine CTRL a me D. E hōʻike kēia i nā totals no kēlā faila.

Hoʻopili kēia i ke kauoha e loaʻa me ka hua'ōlelo helu helu. Loaʻa ka palapala i loaʻa i loko o ka papa inoa o kēia manawa (e hōʻikeʻia ana e.)
