I could\'nt find a solution to a problem that has been hindering the use of notepad++.
When you double click text to highlight that text and others like it,
I don't know that option in Notepad++ yet. Since, you've asked about any other text editor that does so, I would recommend you to use Sublime Text. It's a really cool text editor with lots of smart features. I bet you'll love it. By default, it does not treat the hyphenated words as a single word. But it's way too easy to customize the setting for that. All you need to do is go to 'Preference-> Setting-Default', where you'll find the following setting:
"word_separators": "./\\()\"'-:,.;<>~!@#$%^&*|+=[]{}`~?",
From there, just remove the hyphen and we're done!
