When I’m in Mac OS X, I’m able to switch tabs in my browsers and in TextMate using a Command- keybinding. If I want to go to the first tab, I use Command-1, second tab Command-2, etc.
Is there a key binding in Eclipse based IDEs that will support this same functionality?
Eclipse doesn’t support a tab-index-based navigation. The default editor switch key binding as noted by other responders is CTRL+F6. You can configure this to your liking (Window > Preferences > Keys: Next Editor).
Another way to switch between editors is to use CTRL+E. This presents a dialog with all open editors. You can type in the name of the one in which you are interested. This comes in handy when you have numerous open editor tabs (and Eclipse has hidden tabs it is unable to show).
