Cut and Paste Latin & Cut & Paste surprises.
In Immersion, the Spanish document on Gunpowder ( http://duolingo.com/#/translation/056bdb99176efc6c79cd5411e398d294 ) contains Latin text. I assume I need to Cut and Paste the Latin into the edit window.
Note also, when one cuts and pastes immersion text, there may be some surprise mouse-over translations embedded in the copied text, so it's necessary to carefully proofread the text and delete these extra goodies.
I found a solution for the 'cut & paste' problem, I go the the linked original page (right side of screen) and copy & paste from it if I need/want to copy a lengthy item.
