      Description

      Regular expressions are a powerful tool when finding or replacing code. However, the power and flexibility come at a price: Even simple expressions can be non-obvious to casual users. In addition, the documentation is so overwhelming that it's hard to find these simple expressions quickly.

      Suggestion: Make it easier to use such simple expressions such as
      -) match any character
      -) match any number
      -) match any string of characters
      -) match any string of whitespaces
      -) match a line break

      Possible way to achieve this:
      1) Add a little drop-down box in the find/replace dialog from which you can select and insert a few ready-to-use regular expressions and characters that need to be escaped
      (see the Visual Studio 2015 Expression Builder for an example, although I would cut down to around 10 expressions for that)
      2) Provide a shortlist of popular regular expression in the documentation
      3) Provide a simplified regular expression option that only allows a few expressions, and that is modeled on well-known existing system (? to match single character, * to match any string, \n to match line break,...)
      (see Notepad++ for an example)
