While using Vim I'll sometimes want to look at a function definition or a struct definition, so I'll use C-] to jump to it. However, there are a few problems I run into. First off, I don't know how to jump back easily. It appears the previous file I was in closes and I'm now in the new one. Is there a way to jump back, or keep a stack of open files that I can pop back to or something?
Another thing I've noticed that when I have a change in the current file I need to save it because, like a mentioned a moment ago, my current file is being closed before the next one opens.
And sometimes I want to view my current code and my header at once. Is there a way open the tag definition in a split?
Add
set hidden
to you vimrc. It'll allow you switch files without saving them. I think this is one of 'must have' options.
Use C-o to jump back to previous locations which were autosaved in a jumplist.
:h jumplist
To jump back from C-], use C-T. The :tags command shows the current stack.
Set the autowrite option to automatically save what you're doing before jumping to a new file.
Use C-W C-] to open the tag in a new window.
Finally, :help tags is the section in help that explains all this and more.
Another useful feature that comes handy is the uppercase marks. These marks are not local to a buffer and can be used to jump to them from across files. If you mark the line as say "A" using mA command before starting a long and arduous jumping around task, you can finally return back to the original position quickly by typing 'A or `A.
You might want to consider using a few vim extensions that make this even simpler.

These require that vim was built with +ruby.
% vim --version | grep +ruby
They're very useful for staying in vim and jumping between files.
