In this case, you are not just referencing the first captured group in replace pattern, but also in the search pattern itself by \1. They will allow you to find consecutive duplicate words like this: This means you want to reference a group captured in the preceding part of the search pattern in the later part of the pattern. Removing duplicitiesįor this task, you will need backreferences in the search pattern. In a same way you can use $ for the end of the line. There are no capturing groups in the sample, just an anchor metacharacter ^ indicating the beginning of the line. The following sample will find all occurrences of the word Note: only if it's at the beginning of the line and transforms it to > **Note:**. header html tags text into a different text - # text a markdown header.

The groups are delimited by parentheses () and then referenced by the $number in the replace pattern. What most of the samples below have in common are capturing groups in the search pattern. I would rather show a few examples, so you will get a feel for how it can be useful to you. I don't want to explain regular expressions in detail, I think there are plenty of other resources on this topic. The dialog in Visual Studio looks like this: If you want to search through the files, not just the current document you will want to press these: Some users have reported that Alt+R did't work since it's bound to toggle the NVIDIA display of stats.
