After doing some more reading I think I understand, which, in part, was my not knowing exactly how it worked with my other programs as far as editing. So please let me know if this is incorrect.....I can not save a pdf or ppt in evernote and change the actual format unless I open it in preview for pdf or keynote for ppt. I make my changes and then save it back to evernote. I was thinking I could just click in evernote and make the changes right inside the note. Also, I've read many people just use Dropbox to do all the editing and then save the final document in Evernote. I opened my ppt lecture and saved it as a pdf and then copied that into evernote, I changed it to show as an attachment but when I opened the note to make changes it wouldn't open in preview for some reason, so I guess I'll just keep playing around with that. My next question is......do I need to save all the pdf's inline, or can I save the pdf's as an attachment and they still be searchable? Same with powerpoints, do I have to copy each slide into the note for it to be searchabe, or will it search the ppt in attachment form?
