How to use the Datepicker widget:

The datepicker can be implemented as an inline datepicker or as a popup datepicker.

Inline datepickers have a separate tab stop for each control, and a single tab stop for the date grid itself. The grid can be navigated using the following shortcuts:

• Arrow Keys: Move up, down, left or right in the grid. If the beginning or end of the month is reached, the grid will automatically change to the next or previous motnh
• Enter Key: Select the currently focused day
• Home: Move focus to first day of the month
• End: Move focus to last day of the month
• Page Up: Switch to previous month
• Page Down: Switch to next month
• Alt + Page Up: Switch to previous year
• Alt + Page Down: Switch to next year

Popup date pickers have the same shortcuts as inline datepickers, plus the following shotcuts:

• Down or Up Arrow key (when text field has focus): Move focus into the expanded date grid
• Escape key (when text field has focus): Collapse the expanded date grid
• Enter (when date grid has focus): Select currently focused date, collapse the date grid and move focus back to the text field
• Escape (when date grid has focus): Collapse the date grid without making a selection and move focus back to the text field
