NETBEAN KEY PROBLEMS – Stack Overflow in Spanish

Before in netbean to position the keyboard course (|) in the start or end key of a function or method it was placed in a yellow color that served me to see which key corresponded to the one indicated, that is, he was in the first one (and he had another 3 that followed him but he was also in yellow) that corresponded to the first one. if you know how to reactivate that works, I would appreciate it
