Brackets: select text string occurrences by double click

Solution 1:

Found what you need. It is called Quick Search
Go to https://s3.amazonaws.com/extend.brackets/enturn.quick-search/enturn.quick-search-1.1.3.zip
And Install it. It is an occurance highlighter as mentioned Automatically highlights occurrences of the selected word (like Notepad++ smart highlighting)

Found that from : https://brackets-registry.aboutweb.com/

Solution 2:

There's now an official Brackets feature for this, but you have to enable it in your preferences:

  1. Choose Debug > Open Preferences File in the menu
  2. Add a new top-level entry "highlightMatches": true
  3. Save the file and you're done!

You can also set it to "highlightMatches": {"showToken": true} if you want it to highlight without even making a selection first (just based on cursor position alone).
