So  your goal is to search and replace According to the Official Visual Studio s keyboard shotcuts pdf  you can press Ctrl   H on Windows and Linux  or   F on Mac to enable search and replace tool    If you mean to disable the code  you just have to put  lt h1 gt  in search  and replace to        But if you want to use this regex instead  you may enable it in the icon   and use the regex   lt h1 gt       lt   h1 gt  and replace to        1   And as  tpartee suggested  here is some more information about Visual Studio s engine if you would like to learn more    Find and Replace Window  documentation  Quick Replace  Find and Replace Window  documentation  What flavor of Regex does Visual Studio Code use

For beginners  I wanted to add to the accepted answer  because a couple of subtleties were unclear to me   To find and modify text  not completely replace     In the  Find  step  you can use regex with  capturing groups   e g  your search could be la la la  group1  blah blah  group2   using parentheses    And then in the  Replace  step  you can refer to the capturing groups via  1   2 etc      So  for example  in this case we could find the relevant text with just  lt h1 gt     lt   h1 gt   no parentheses   but putting in the parentheses  lt h1 gt       lt   h1 gt  allows us to refer to the sub-match in between them as  1 in the replace step   Cool     Notes   To turn on Regex in the Find Widget  click the    icon  or press Cmd Ctrl Alt R  0 refers to the whole match Finally  the original question states that the replace should happen  within a document   so you can use the  Find Widget   Cmd or Ctrl   F   which is local to the open document  instead of  Search   which opens a bigger UI and looks across all files in the project
