    I have a text file where there are a lot of numbers right next to a letter. It may appear like this: "9999The best"

    How do I put a space in between all of the instances when a number is next to a letter?

    Thanks,

      Unix regular expression mode

      Find String ([0-9])([A-Z,a-z])
      Replace String \1 \2
