Hi,

 

Is there any way that i can search for any text in a class/page while working in Developer Console. I have a long class with thousand lines of code and need to find some specific text in that class. Browsers 'Ctr + F' does not works. It only shows me the search results from the few lines of code that is visible on the page.

 

Does DC provides any search text box which i am missing which i can use to search the text from my code?
