Perhaps this is a trivial question, however it's something that is seriously annoying me. I'm editing someone's program at the minute and one of their .java files is absolutely massive. I'm trying to edit it at the moment, whilst referencing it as well.
Is it possible to split the screen in Eclipse, to allow a split view of the same file?
Window -> New editor
Then drag the new tab to the right until you see an arrow, then lift your finger. Doing it this way the two views will be in sync: everything you change on the left will change on the right. Is this ok for you?
I have implemented small plugin which can split view for any eclipse based editor and make a video have it's work, see video here http://www.youtube.com/watch?v=61yJF7LQ-bE. This plugins part of jboss tools, but can be installed. With it you can split editor view just by clickin CTRL+8 or window->New Editor(Side By Side).
