2, don't worry, I'll teach you how to find, press CTRL+F, enter the object you want to find, the number 1 or the lowercase letter L, find the object will be highlighted, so you can determine whether the highlight is the number 1 or the letter L

3, of course, so every time to find, always feel inconvenient, then you can set up a clear font of their own to be able to, after each time you can directly find this is the letter L or number 1

4, I use Microsoft ya Black to be able to divide clearly, and individual also think Microsoft Elegant black font looks compare input, do not believe? You try!

5, look at my settings after the information, hurriedly try it!
