Switching Tabs In Eclipse 7
I found it!
Well, not really. I asked people who told me. After expending far too much time searching through key listings and web pages, and wearing out my welcome by asking my friends who have been using the Eclipse editor for quite a while, I finally remembered that there's an IRC channel where helpful people lurk in order to help clue-free noobs like me. Maybe I've been listening to the commercial world too much, but somehow it managed to escape my notice that open source software really does have support, and darned quick support. I think maybe it's unwise to deny programmers access to open source, and it's certainly unwise of any company using open source to not allow access to the support forums. It is often the shortest distance between here and productivity. If it were commercial software, I doubt I would have waited for an hour on a tech support line (and paid for the time) in order to ask productivity-enhancing questions. I would tend to save the support calls for "real problems."
The answer to the problem of switching between editor tabs is Control-PgUp and Control-PgDn.
The answer getting a quick answer to prob lems is #eclipse at freenode.net. Thanks to the good people there, esp "buggs".

I also mapped the Ctrl + Tab sequence to the “Next Editor” command. This allows you to toggle between the current and previous tab a la other Windows programs as well as select a particular tab from a list.
There is also Ctrl+E to see a list of open editors (works kind of like quick outline); CTRL+F6, to toogle between editors similar to windows ALT+TAB; CTRL+F7, to toogle between open views and CTRL+F8 to toogle between recent perspectives.
I was a little unhappy when I realized it switches between tabs in the current tab control, not strictly in the editor. I have to switch to the editor before it goes between tabs. A small problem.
When switching back and forth between only two editors (e.g. test and target), Ctrl-F6 seems to work best for me…
I think Ctrl+F6 is the real answer to your problem, but I find it way too uncomfortable. I prefer the solution given by Chris in the first response.
Next/Previous Ctrl+PgDown -> Changes to file to the right Ctrl+PgUp -> Changes to file to the left
you can find it here !!!

I agree with:
“I think Ctrl+F6 is the real answer to your problem, but I find it way too uncomfortable. I prefer the solution given by Chris in the first response”
Remember to remove the CRTL+F6 binding, else it won’t work.
