Steps to reproduce the problem:
1. open the Elements tab in dev tools
2. in the dom pane, try to search for 'Back'

What is the expected behavior?
I want it to only match 'Back' - ie be case sensitive

What went wrong?
It matches 'back' too, for which there are many more references.

Did this work before? Yes 15.0.874.15

Chrome version: 63.0.3239.132  Channel: stable
OS Version: 
Flash Version: 

This is relevant (that's where I got the latest version it worked):

IMO, it should be possible to specify case - it is extremely useful in big files.
Some editors have a feature called 'smartcase'[1], where the word is not case sensitive until the user types a mixed case search - ie 'back' will match both 'Back' and 'back', but 'Back' will only match 'Back'. That would be my preference.

An alternative would be to make it a regex, or provide a checkbox for case sensitivity (or insensitivity). I see there is a 'Aa' icon to do that in the 'Sources' tab, so I guess that would make sense.
