In Visual Studio as well as in other applications I enjoy the MRU tab system (Most Recently Used) which allows me to jump back and forth between two tabs I’m working with instead of simply jumping to the next tab. This can be annoying if you have 5 tabs open but currently only work with tab 2 and 5; you don’t want to jump to the next tab, you want to jump between tab 2 and 5.
This can be done in eclipse as well. The default binding is Ctrl + F6 (Next Editor) and Ctrl + Shift + F6 (Previous Editor). Just go to Window => Preferences => General => Keys and search for F6 or next/previous editor and change the key binding to Ctrl + Tab and Ctrl + Shift + Tab.
