I want to translate the “esc” string in the admin panel, but it seems not to be there.
I mean the esc that is written top right of the blue message in the composer (it’s in several similar educational messages):
can someone help me if you know the code.name of the string?
The reason you can’t find it is because we’re not using an actual string here, but we should be.
It’s currently set in CSS here
We’ll get that sorted, but you can add this to your theme if you want a quick fix.
.composer-popup {
a.close:before {
content: "esc"; // change to the desired text
}
}
thanks 
that was handful.
