I made a very good eraser, but I'm new here and I can't post photos and links, you can greatly reduce your code, use variables and not numbers on the clicks, don't throw the click to the trash but use the "Middle" to Instead of LEFT or RIGHT, it erases the item.
example.
Sleep % tempo_150
Click, %coluna_5%, %linha_10% Middle, Down
Sleep % tempo_100
Click, %coluna_5%, %linha_10% Middle, Up
Sleep % tempo_150
Click, %confirmacao_coluna%, %confirmacao_linha% Left, Down
Sleep % tempo_100
Click, %confirmacao_coluna%, %confirmacao_linha% Left, Up
