In Aptana Studio, instead of using Alt+Tab to navigate through a series of open files, use the keyboard shortcuts Ctrl+Tab and Ctrl+Shift+Tab to navigate between files that you have open in the editor.
- To go to the next file open in your editor, use the shortcut key combination of Ctrl+Tab or click the Forward button in the toolbar.
- To return to the previous file open in your editor, use the shortcut key combination of Ctrl+Shift+Tab or click the Back button in the toolbar.
Note: You can also access this feature from the Window menu by selecting Navigation > Next Editor or Navigation > Previous Editor.
