Sparklines and more charts in Spreadsheets

The following new features are now available in Google Spreadsheets:
- Sparklines: These let you display line or bar charts inside of cells and are useful for presenting and comparing data in a simple, in-cell format.
- More chart options: New charts and options including different Y-axes on either side of the chart, formatting options for the axis and title text, and other customization for how lines, bars, or pies are displayed.
- Keyboard accelerators, mnemonics and shortcuts: Keyboard accelerators let you open menus using special keyboard shortcuts. A mnemonic lets you choose a menu item with the stroke of a single key, and it’s indicated by an underlined letter in a particular menu. After you open a menu using a keyboard accelerator, use a mnemonic to select an item in the menu.
