For beginners  the accepted answer is correct  but a little terse if you re not that familiar with either VSC or Regex     So  in case this is your first contact with either    To find and modify text     In the  Find  step  you can use regex with  capturing groups   e g  I want to find  group1  and  group2   using parentheses   This would find the same text as I want to find group1 and group2  but with the difference that you can then reference group1 and group2 in the next step   In the  Replace  step  you can refer to the capturing groups via  1   2 etc  so you could change the sentence to I found  1 and  2  having a picnic  which would output I found group1 and group2 having a picnic      Notes     Instead of just a string  anything inside or outside the    can be a regular expression     0 refers to the whole match
