How to search for a language string?

Hi,

I go to admin section, Settings, Language Settings, Keys

I am typing in an language string (like "_sys_bm_language"), the apply checkbox gets checked automatically and then you have to press enter? Whats this?? And it still has no trim :(

The old procedure was complicated but compared to this it was gold!

And how to search for something thats not a string, like I know how it is translated but not what the string is?

You're doing it correctly, I'm not sure why they needed us to check the box AND hit enter but it looks like that's how it works now. 

It looks like some sort of bug:

Check my modules page, maybe something will help you out with it. I've made the interface to work with translations.
