Hi, I did a code with a text input and an example external file ("list.txt", that contains few words: arancia, banana, MELA, melanzane).
At the moment if you type "red", the background color changes for a while. But I'd like to write a code where if the last typed word is equals to one of the word in the external file, then the background color changes. (it should be a sort of finder)
How could I do it?
