		<a class="head1" href="#bktop" name="intro">Introduction</a>
		AppsTML Sinhala Keyboard a is single file browser-based application that enables you to type in Sinhala to a user defined textarea. 
		The typed content can be cut and pasted to (as well as pasted from) MS applications (windows, word, 
		notepad, wordpad, etc.) , internet applications ( e.g. e-mail, textboxes in html documents, etc. ) and other applicable 
		programs. It operates off-line thus an internet connection is not needed. Requirements 
		for satisfactory operation of the application is listed in subsequent sections.
		
		 
		<a class="head1" href="#bktop" name="sysrqmt">System Requirements</a>
		<ul>
			<li>Given that the application runs via an internet browser, a functioning 
			browser program is essential (internet connection is not required). 
			The functionality and the appearance of the program will vary with the 
			browser and version. Internet Explorer 8+ and comparable browsers should 
			enable the application to function as intended. Earlier versions may 
			produce none or partial functionality.</li>
			<li>System requirements in terms of the speed, memory, etc. for the application 
			itself is insignificant compared to the requirement of the browser program 
			and Sinhala language support (<a href="#SinLanSup">see details</a>).
			</li>
			<li>The layout of the keyboard was arranged with a minimum screen resolution 
			of 1024 x 768. Display settings of a lower resolution is likely to produce 
			irregular results. In such cases consider an adjustment of the browser window 
			zoom feature and <a href="#wkspcsu">workspace setup</a> in the AppsTML Sinhala Keyboard. </li>
		</ul>
		<a class="head2" href="#bktop" name="SinLanSup">Sinhala Language Support</a>
		In order to view Sinhala script on the on-screen keyboard and textarea, 
		the computer must have Sinhala language support. MS Windows Vista and subsequent 
		releases of Windows have Sinhala language support. However, 
		Xp and older versions of Windows require Sinhala language support (Sinhala 
		Unicode) to be installed from an external source. Sinhala Unicode support 
		kits are available to download from sources such as:

		<a class="head1" href="#bktop" name="OScrnkbrd">On-Screen Keyboard</a>
		Mouse click on a key (button) in the on-screen keyboard generates the character 
		in the allotted textarea. The character is generated as the last of the 
		content in the textarea (irrespective of the position of the cursor). Clicking 
		an on-screen keyboard key cannot generate a character in the middle of the 
		content in the textarea. Inserting a character or characters (ie. words) 
		within the content in the textarea a requires different procedure (<a href="#insttext"> 
		see Inserting text</a>). Such restriction do not apply when inserting text 
		via pressing keys on the physical keyboard. Other keys in the on-screen 
		keyboard:
		<ul>
			<li>Clear All – Deletes all content in a textarea.</li>
			<li>Delete (last) – Deletes the last character in the main textarea 
			(irrespective of the cursor position). To delete characters 
			within the contents in the textarea use the appropriate key (ie. Backspace 
			, delete) in the physical keyboard. </li>
			<li>Space – Creates an empty space in the last position of the textarea 
			(irrespective of the positioning of the cursor).</li>
		</ul>
		<a class="head2" href="#bktop" name="kbrdarng">Sinhala Script Keyboard Arrangement
		</a>
		<ul>
			<li>Characters in the second row (except ෆ) can be considered the vowels 
			in the Sinhala alphabet. </li>
			<li>Characters in the third and fourth row (and ෆ) are consonants.</li>
			<li>The fourth and fifth row contains characters that are termed as 
			the signs (or vowel signs) of the Sinhala script. Signs are attached 
			to consonants to produce vocalic variations. </li>
		</ul>
		<a class="head2" href="#bktop" name="TpSinScr">Typing in Sinhala</a>:
		<ul>
			<li>Vowels are typed in as a single character. Signs generally are not 
			conjoined to vowels.</li>
			<li>Consonants should be typed before the sign even if the sign appears 
			prior to the consonant in sequence of characters ( e.g. ක then ෙ produces 
			කෙ).</li>
			<li>Special signs,්‍ර 
			(or ්ර) and
			්‍ය(or 
			්ය) should be typed in straight after the consonant. Additional signs 
			can be inserted thereafter. </li>
			<li>Certain signs keys produces varying character shapes based on the attached consonant
			 ( eg. ම + ු → මු whereas ක + ු → 
			කු and ක + ් → ක් whereas ම + ් → ම් )</li>
		</ul>
		NB: AppsTML Sinhala keyboard does not contain all the characters used 
		in the Sinhala script. However, attempts were made to ensure that most frequently 
		used characters in the alphabet are available. Those that do not appear 
		could be inserted into the textarea by changing the language setting of 
		the physical keyboard and pressing the appropriate keys.
		 
		<a class="head1" href="#bktop" name="wkspcsu">Workspace setup</a>
		AppsTML Sinhala keyboard allows you to resize the main textarea and change 
		the font size in the textarea. Simply replace default values and click ok 
		to change settings.
		<ul>
			<li>Width – The default width of the textarea is 80% (percentage of 
			screen size). It can be increased (e.g. 150%) or decreased (e.g. 50%) 
			as a percentage or another appropriate unit of measurement (e.g. 500em, 
			1000px ect. ).</li>
			<li>Height – Change the height of the textarea from the default (200px) 
			by replacing the value to a desired height in an appropriate unit 
			of measurement (px, em).</li>
			<li>Font size – Is the size of the font in the textarea/s . It is not 
			the size of the font that would appear once pasted to a html or text 
			document (e.g. word document). The option was created to allow the user 
			to view the content at a desired font size. </li>
			<li>Fixed keyboard and menu - Checking the selection box locks the keyboard 
			and menu in to a fixed position on the screen. </li>
			<li>Default button – Returns editable values back to default settings.
			</li>
		</ul>
		 
		<a class="head1" href="#bktop" name="mnftrs">Menu Features</a>
		Undo/Redo – The undo button can retrieve content from upto 10 previous 
		actions. The redo button returns the content back to the original from an 
		undo step.
		<a class="head2" href="#bktop" name="insttext">Insert text</a>
		Sinhala script keys on-the screen keyboard cannot directly insert content 
		to any position within the textarea. However the application does have a 
		feature which allows you to insert text to a selected position. It utilises 
		a secondary textarea (smaller textarea located besides the menu buttons) 
		which can be activated by clicking the "main textarea" button. Upon activation 
		the text on the button changes to “secondary textarea” and the background colour of the secondary textarea changes. 
		Now if a key on the on-screen keyboard is clicked, the corresponding 
		character is inserted in the secondary textarea. The main textarea is deactivated 
		from the on-screen keyboard, but mouse actions and physical keyboard operations 
		are still active. Text content can be inserted into desired position in the 
		main textarea via the following steps: 
		<ul>
			<li>Type the required content in the secondary textarea.</li>
			<li>Make a selection in main text area (It must be a selection spaning 
			at least a single space. Placing the cursor on specific location is 
			ineffective. Selection could even be an empty space within the textarea.)
			</li>
			<li>Clicking "Insert Text" button should insert content from the secondary 
			textarea to the initial position of the selection.</li>
			<li>Alternatively you can copy the text from the secondary textarea 
			to the clipboard and then paste to the desired location within the main 
			textarea.</li>
		</ul>
		To deactivate the secondary textarea, click the “secondary textarea” 
		button. Text and colour should revert back to the original.
