Switching to landscape mode in Android Emulator

Not sure about your question - "sideways" is the same as "landscape".

If you mean how to switch during runtime:

• Switch to previous layout orientation (for example, portrait, landscape): KEYPAD_7, Ctrl + F11
• Switch to next layout orientation (for example, portrait, landscape): KEYPAD_9, Ctrl + F12

From docs.

Try:

• ctrl+fn+F11 on Mac to change the landscape to portrait and vice versa.
• left-ctrl+F11on Windows 7.
• ctrl+F11on Linux.

For Mac users, you only need to use the fn key if the setting "Use all F1, F2 etc. keys as function keys" (under System Preferences -> Keyboard) is checked.

• left-ctrl+F11on Windows 7 It works fine in Windows 7 for android emulator to change the landscape orientation to portrait and vice versa.

Just use 9 in numeric keyboard with num-lock off.

7 rotates in the opposite direction.
