I want to know the answer to the following question:
What is the purpose of charms?
All the background I'm provided with is that "A vertical toolbar known as the charms (accessed by swiping from the right edge of a touchscreen, or pointing the cursor at hotspots in the right corners of a screen) provides access to system and app-related functions, such as search, sharing, device management, settings, and a Start button.". Is that enough to answer the question?
Answer: yes
