 3. __Solve the puzzle__ using pencil marks, cell highlighting, guesses, hints, and if all else fails, show solution.
 
 ##Button/link descriptions:
-*__Begin solving__: Sets the entered values as read-only clues and submits them to the puzzle solver. Once the values have been submitted, they cannot be changed. This generates a solution for the values and enables the solving features.
-*__Save/Load__: Shows a panel with options to save a sudoku puzzle in progress or reload a previously saved puzzle.
-*__Save/Load>Input Puzzle__: Allows values to be inputted from the clipboard. This overwrites existing values. Zeros, "*", ".", or "_" can be used as placeholders for empty cells. All other characters are ignored. There must be exactly 81 numbers for this to work properly.
-*__Save/Load>Import State__: Paste a text string copied from __export state__ to reload the state of the puzzle when the text string was copied. This overwrites existing values.
-*__Save/Load>Save to Cookie__: This saves the values, pencilmarks, and cell number coloring to a cookie. Cookies must be enabled in the browser.
-*__Save/Load>Load from Cookie__: If a previously saved cookie exists, this reloads the values, pencilmarks, and cell number coloring stored in the cookie. Overwrites existing values.
-*__Clear cells__: Deletes all values, resets pencil marks, and removes all highlighting. This resets the page to its initial state.
-*__1-9__: Highlights all cells that do not have a pencil mark of 1-9 a pale green color. If the pencil marks have been updated, this can be used to easily determine which cells do not have a value of 1-9. Does not update automatically.
-*__Clear__: Removes all cell highlighting.
-*__Enter values__: When this option is selected, typing a number in a cell changes its value.
-*__Enter pencil marks__: When this option is selected, typing a number in a cell toggles the corresponding pencil mark.
-*__Automatically remove pencil marks__: When this option is enabled, entering a value in a cell removes that pencil mark from all of the cell's neighbors (cells in the same row, box, or column).
-*__Update__: Changes all pencil marks so that they show the possible values that each cell could have. This overwrites existing pencil marks.
-*__Reset__: Adds all pencil marks to empty cells. Allows solving the puzzle without the aid of pencil marks. This overwrites existing pencil marks.
-*__Show duplicates__: When this option is enabled, neighboring cells with the same value are flagged red.
-*__Mark blank cells (color)__: Marks all blank cells with a certain color. Use this to make guesses so that if the guess is incorrect, all values entered afterward can be removed easily.
-*__Delete cells marked (color)__: Deletes all cells that have been marked a certain color. Does not affect cells marked a different color or pencil marks.
-*__Show solution__: This opens the sudoku puzzle's solution in a new window. If there are more than one solution, only one will be displayed.
-*__Hint__: Gives a hint for cell that was last selected, up to three hints. Hints are based on the solution.
