I am trying to translate a site to French, I installed language pack plugin. There still has many sentences are not be translated.

For example: 

"...are now friends" = {text key='friends+newsfeed_action_string'}

"...edited their profile details" = {text key='base+feed_user_edit_profile'}

When I was trying to find these key in Language> Available languages> French, I cannot search them by text key. It's 200 pages of missing translation list. How could I find those?

Any way to export/import translation file?

Note: I am using Oxwall paltform version 1.6.0 (build 7157)
