Just installed MODx revolution beta (went like a breeze

) and now I’d like to get a french translation out very fast of course... Let me tell you even as someone who tested the alpha early on, I am totally in awe by the work Jason, Shaun and the team has done for the beta !
Back on translating, I am not sure how to go about this. I checked out
System > Lexicon Management but I am still unsure about the way to proceed here (if translators who have done this can help me here). I have read
http://svn.modxcms.com/docs/display/revolution/Lexicons and related pages but this doesn’t tell me how to actually build a translation.
When I am on the english page, I select with dropdown "fr" :
Then I am a bit puzzled, I don’t "see" any strings :
So I look and see the create dropdown menu :
If I understand correctly, I have to create a topic (quote the doc "A Lexicon Topic is a collection of Lexicon Entrie") and I guess namespaces remain unchanged for alternate languages (I mean if I translate "core" I still keep the namespace "core" ?).
What I fail to see is how I match the translation terms to the the terms being translated. In terms of UI, I’d have expected to see original strings in a column, and the empty french strings in an adjacent column.
My question is, how do I proceed ?
Do I export the english language, translate the file and then import ?
Thanks !
