How to remove duplicate lines in Visual Studio Cod

Question

Say you have the following text:

abc
123
abc
456
789
abc
abc

I want to remove all "abc" lines and just keep one. I don't mind sorting. The result should be like this:

abc
123
456
789

Here is a very interesting extension: Transformer

Features:

• Unique Lines
• Unique Lines As New Document
• Filter Lines
• Filter Lines As New Document
• Sort Lines
• Sort Lines By Length
• Align To Cursor
• Align CSV
• Compact CSV
• Copy To New Document
• Select Lines
• Lines As JSON
• Trim Lines
• Count Duplicate Lines As New Document
• Macros

For removing duplicate lines:

• Removes duplicate lines from the document

• Operates on selection or current block if no selection

I haven't played with it much besides the "Unique Lines" command but it seems quite nicely done (including attempting a macro recorder!).
