The integrated development environment includes numerous tools and options that help you manage windows in the integrated development environment (IDE).
The IDE supports two different interface modes: Multiple Document Interface (MDI) and Tabs on documents. You can changes modes using the General pane under the Environment options in the Options dialog box.
Multiple Document Interface Mode
In MDI mode, the IDE provides a parent window that serves as a visual and logical container for all tool and document windows.
Tabs on documents mode
This mode tabs document windows together. The IDE uses this mode by default.
Tip Use CTRL+TAB to cycle through the documents open in the editor. CTRL+TAB works similarly to ALT+TAB, cycling through the most recently used open documents.
