1: I have copied the original Nisus Writer Pro folder to the Applications Support folder in my (user) library on the new machine but I seem to have lost all my shortcuts. What have I done wrong?
Copy the following files from your old machine to the corresponding location in the new one:
~/Library/Preferences/com.nisus.NisusWriter.plist
~/Library/Preferences/com.nisus.NisusWriter.LSSharedFileList.plist
2: this is a question I have asked in the past: how do you get back to previous insertion points in Nisus Pro?
⌘] Edit:Select:Previous Selection takes you to the previous selection(s) or cursor location(s).
⌘[ Edit:Select:Next Selection returns to more recent selection(s) or cursor location(s)
