To install the mod:
	1 - Extract the ZIP file to a temp folder your local drive
	2 - Open the temp folder and upload the scroll_mod_v14.0.3.5.cfg file to the TNG mods folder. (This is a FILE NOT A FOLDER)
	3 - Open the temp folder and upload the scrollmod_v14.0.3.5 FOLDER, NOT THE ZIP file, to the TNG mods folder. (This is the complete folder not individual files)

The scroll mod folder should not contain any subfolders, only files. Using the admin console, go to the TNG folder on you website.
Confirm the scroll_mod_v14.0.3.5e.cfg file and scrollmod_v14.0.3.5e folder are in the mods folder.
Log in to TNG and go to the admin page and select Mod Manager.
If the scroll mod cfg file is present the line will display "OK to install".
Note you will not see the scroll mod folder from the mod manager window but if the folder is missing the line will display "Cannot install".

Locate the line containing scroll mod a click on OK to install. When the line expands select INSTALL.

After the scroll mod is installed, the scrollmod_v14.0.3.5e.zip file can be stored on your local drive and the mod contents in the temp folder deleted.

After installing Scroll Mod, REFRESH (Ctrl-F5) the page to reload the style sheets (css files). Otherwise the buttons may be large or in the wrong position.

When pages have vertical overflow, up to four buttons appear depending on the page height. 
On pages with horizontal overflow but no vertial overflow, up to four buttons appear that scroll left and right.
If the page has vertical and horizontal overflow, up to eight buttons appear. 
The number of buttons shown depends on the amount of overflow. So when content requires more than one click more buttons appear that scroll to total height and/or width.
If the page has no overlow, buttons do not appear.

Scroll mod uses a scrollconfig.php located in the TNG root folder. This file contain two different arrays that control which pages can be scrolled. The arrays are as follows:
$scroll_none - Files listed in this array are not scrolled. There are no options for using this array. The files must be edited manually using a source code editor to make changes. DO NOT USE A WORD PROCESSOR OR TEXT EDITOR THAT ADDS AN EOL CHARACTER TO MAKE CHANGES. If you do not use a source code compatible editor text editor or make a syntax error in the array, TNG will not show anything and you will get a PHP error. If this occurs simply delete the scrollconfig.php file, uninstall and then reinstall the mod.

$scroll_select - Files listed in this array are always scrolled if content overflows. This array has priority over the $scroll_none array. Using this array is controlled in mod option 3 listed below.

Mod options are as follows:

Option 1 - Scroll Vertical Distance
Enter the vertical scroll distance. The number entered is converted to percent and multiplied by the units calculated from the clients display. Use decimals to fine tune the scroll distance. This allows a consistent experience for different screen resolutions. Keep in mind if you enter 100 the page will scroll the screen height so content at either the bottom or top of the page will scroll out of of view. The valid range is 10 to 100, numbers outside this range will use the default setting of 90.

Option 2 - Scroll Horizontal Distance
Enter the horizontal scroll distance as percent. The number you enter is converted to percent and multiplied by the units calculated from the page or clients display width. Use decimals to fine tune the scroll distance. This allows a consistent experience for users using different resolutions. Keep in mind if you enter 100 the page will scroll the page or screen width so content at either the right or left will scroll out of of view. The valid range is 10 to 100, numbers outside this range will use the default setting of 90.

Option 3 - Only Scroll Charts and Select Pages
Use this option to scroll files listed in the $select_only array. Any file not listed in this aarray is ignored.

Option 4 - Hide Scroll Buttons on Home Page
Enable this option (1) to hide the scroll buttons on the home page.

If you use a custom template or want to customize colors, change the button size or move the buttons, refer to the scrollpage-info.css file in this folder for the classes and rules to add to the mytngstyle.css file.

Scroll buttons will not appear on mobile devices unless the device uses a non standard identifier.

Horizontal scroll buttons will not appear on templates 2, 4, 5, 6 and 7 unless the template mod is installed. Note in TNG v14.0.4, template 4 has been updated.

If you want to change the button color, size, opacity, shape or position please read the scrollpage-info.css.

This mod version was updated so GWT templates do not have white space at the top of the page after the mod is installed.

When scrolling you can double click to scroll one page height or width and a partial scroll. This is useful for scrolling large charts.
