'<i>This is a spreadsheet built on SocialCalc JavaScript code. '+
'</i> '+
'<br><br> '+
'You can use the arrow keys and mouse to select cells in a manner similar to traditional spreadsheets. '+
'This includes using the shift key, as well as dragging. '+
'<br><br> '+
'The scrollbars should work in a normal manner. '+
'Because this is a spreadsheet, you can scroll any amount without needing to create new rows or columns. '+
'Dragging the thumb to the end of a scrollbar attempts to go to the last row or column where there is/was data. '+
'The mousewheel is also supported. '+
'<br><br> '+
'In addition to the scrollbars there are two pane sliders (that start out at the beginning of the scrollbars) '+
'that let you "lock" the upper rows or columns to facilitate keeping column and row headers visible when scrolling. '+
'<br><br> '+
'You can type values in cells. '+
'Press Enter, use an arrow key, or click on a cell to finish. '+
'If you are in a partial formula (e.g., "=1+" or "=SUM(") an arrow key or cell click will '+
'insert the name of the newly selected cell into the formula, similar to a traditional spreadsheet. '+
'Cell ranges are separated by typing a ":", or you can use the drag or shift-click range selection methods. '+
'<br><br> '+
'The program supports many forms of data, such as numbers, text (preceded by a "\'" if necessary '+
'to distinguish it from numbers), dates (e.g., "1/2/3"), dollars ("$1,234.50"), time ("3:45"), '+
'numbers with fractions ("1 1/2"), and "true", "false", and "#N/A". '+
'A value\'s type determines its displayed format if there is no explicit numeric format set for a cell. '+
'The program supports a wide variety of formats (including other currencies) through its custom format functionality '+
'available on the Format tab. '+
'<br><br> '+
'Use the Esc key to cancel during edits. '+
'The Del key deletes the values of the selected cell(s). '+
'<br><br> '+
'The 109 formula functions that the June 2007 Open Document Format "Open Formula" specification '+
'calls the "small group" are available. '+
'(<b><i>A simple reference to all of the functions is provided when you click the "f()" button on the formula bar.</i></b>) '+
'The specification says that: "This group includes approximately 100 functions, '+
'and includes the basic functions that are very widely implemented in spreadsheet applications, '+
'even in resource-constrained environments."<br><br> '+
'The definitions of the functions follow common conventions, '+
'with common syntax similar to many other spreadsheets. '+
'You can, for example, have a function like IF(B10=B3, "Yes", "No"), where B10 and B3 may contain text values '+
'(comparisons are not case-sensitive). '+
'<br><br> '+
'This release has an HTML version of an editing interface. Most buttons on the toolbar display tooltips when you point to them with the mouse pointer. '+
'<br><br> '+
'The program maintains an undo stack accessed through the Undo and Redo buttons on the left of the Edit tab toolbar. '+
'Right now the stack saves up to 50 steps for undoing. '+
'The Ctrl-Z key may be used as a shortcut instead of the Undo button. '+
'<br><br> '+
'There is a <b>Format</b> tab for accessing all of the format settings, both for individual cells as well '+
'as for the sheet-wide defaults that are applied to cells without explicit settings for that attribute. '+
'You can make changes to any or all of the settings and then press the "Save" button in the toolbar above to apply them. '+
'While the cell settings are only displayed for the current cell, on "Save" the same changes are applied to all cells '+
'in the currently highlighted range of cells. '+
'The Sheet settings let you set the default size of columns. To change the width of an individual column click and '+
'drag in the column header. '+
'<br><br> '+
'The <b>Sort</b> tab lets you select a range of cells (which is remembered) to sort, as well as to set which columns '+
'are used to determine the order and the direction. '+
'<br><br> '+
'There is a <b>Comment</b> tab for accessing the optional comment text for the currently selected cell.'+
'<br><br> '+
'The <b>Name</b> tab lets you set named ranges that may be used in formulas.'+
'<br><br> '+
'The <b>Graph</b> tab displays a graph representation of selected cells. It has its own Help button. '+
'<br><br> '+
'The <b>Plain</b> tab shows the sheet rendered without the grid or editing controls. '+
'<br><br> '+
'The <b>Clipboard</b> tab lets you view the SocialCalc clipboard in tab-delimited format, and optionally reload it with new data. '+
'Tab-delimited format is what some browsers and Excel put on the clipboard when you select and then copy cells in a table. '+
'The Clipboard tab also supports CSV format and the SocialCalc Save format (useful for copying from one sheet to another). '+
'Reloading from the SocialCalc Save format must be in correct format -- errors can cause SocialCalc to behave badly.<br><br>'+
'Pressing Ctrl-V when on the Edit tab and not editing a cell assumes that Tab-delimited data is on the regular '+
'clipboard, loads it into the SocialCalc clipboard, and then "pastes" it starting at the current cell. '+
'This is an easy way to copy data from a web page into a spreadsheet. '+
'Similarly, Ctrl-C loads the SocialCalc clipboard and the system clipboard. '+
'Ctrl-V differs from the Paste button in that it only pastes values and formulas, and not formats. '+
'<br><br> '+
'Right now this code is mainly being developed to run under control of a native Python '+
'application running on the OLPC XO. '+
'This version, though, can also be run directly in a browser. '+
'<br><br> '+
'When the program encounters an error, it may display a message at the bottom of the screen. '+
'You can click on the message to erase it. '+
