I have a large PDF file (2000 some odd pages) of transcriptions that needs to be edited. THere are many spelling mistakes etc that i want to fix as i go through but i cant figure out how to edit the text i.e delete and retype, with Acrobat Pro or Preview or anything else. I downloaded 2 PDF editing apps but Iam having the same problem with them. They say they have editing capacity but only seems like you can insert corrections in floating windows ad stuff like that. I dont see the difficulty in just having a simple function that allows you to delete the original letters and then type something else in. Is this not possible or am I just completely lost and doing something wrong? I would just use textedit but when i open this document as a txt file it completely freezes up my computer because i guess its too big. it takes about 10 seconds for it to process simple things like scrolling down. The PDF is really fast about all that but then again i cant figure out how to edit it. Some one in the know please weigh in.
