How do I hide/unhide the taskbar using a keyboard shortcut manually in Windows 7?

Question

I want to use a keyboard shortcut (if possible one which I can choose myself) to manually hide/show the Windows taskbar in Windows 7. I prefer a manual way to set up the shortcut. If this is not possible I take a portable software (one that works from a flash drive) that will do it for me. But in the end I'm open to any suggestions.

I already know about:

• AutoHotkey (individual keyboard shortcut, portable software based)
• Aviassin Taskbar Eliminator (pre-set keyboard shortcut, portable software based)
• RocketDock (software based - installation required)

Please note: this is not a duplicate of this question (which ask how to enable/disable the auto hide feature): Script/Tool to Auto Hide/Unhide Windows Taskbar
