Is it possible to make one key function as any other key??
for e.g. Is it possible to make key1 to function as VOLUME_UP?
Yes this can be done using the API 'SendKeyToTVViewer' API.
1.Unregist the key whose function is to be simulated.
pluginObj.unregistKey(tvKey.KEY_VOL_UP);
2.Let key_1,be used for VOL_UP.
-Declare the object in the html that will drive the API
<object id='pluginObjectAppCommon' border=0 classid='clsid:SAMSUNG-INFOLINK-APPCOMMON' style='width:0px;height:0px;padding:0px;margin:0px;position:absolute;z-index:99;'></object>-Capture the object and use the API.
pluginAppCommon = document.getElementById('pluginObjectAppCommon');
pluginAppCommon.SendKeyToTVViewer(tvKey.KEY_VOL_UP);
3.Use the KEY_1 to function as VOL_UP.
MainKeyHandler = function() {
switch (keyCode) {
case tvKey.KEY_1:
pluginAppCommon.SendKeyToTVViewer(tvKey.KEY_VOL_UP);
break;
}} -
Do you know if the Samsung remote control is sending a special IR code when the batteries are low?
Do you know if it is possible to get this information in the TV from the H Browser?
Currently there is no API to receive the Samsung remote control battery is low.
Only BT Remote supported.

No, this is achieved by RETURN/EXIT key.

What is the best way to identify the key code of the RC key pressed? Is it possible to identify key codes with the
Universal script below, rather than using the Samsung api. Can you pass me all the key codes?
Identification of the key code
In HTML File(inside <body> tag):
<a href='JAVASCRIPT?void(0);' id='anchor'onkeydown='Main.keyDown();'></a>
In JavaScript File:
Line to be called on load of JS:
document.getElementById('anchor').focus();
Function called on ‘onkeydown’event:
Main.keyDown() {
var keyCode = event.keyCode;
alert('Key Pressed = '+keyCode);/* Key Code can be seen in logs */
switch (keyCode) {
/*Cases for different keys here e.g.
case 5:/*Samsung Remote
KeyCode --- LEFT*/
//whatever you want to do....
break;
*/
}
}
(Note: The Key Code detail (http://www.samsungdforum.com/Guide/ref00006/common_module_tvkeyvalue_object.html))

To block Menu and return key, follow the below code:
Include in HTML file:
<script type='text/javascript' language='javascript' src='$MANAGER_WIDGET/Common/API/Plugin.js'></script>
Include in javascript file:
var pluginObj = new Common.API.Plugin();
pluginObj.registKey(tvKey.KEY_MENU);
Handle Return Key-
Main.MainKeyHandler = function() {
var keyCode = event.keyCode;
switch(keyCode) {
case tvKey.KEY_RETURN :
widgetAPI.blockNavigation(event); // Handle return key
break;
}
}

Mouse cursor shows when you insert the USB Mouse plug in TV.
Also you can get the JavaScript mouse events for click.

We use the code below to program the actions associated to the remotes keys.
But, we can't take control or insert some code/actions in some keys.
For ex. - Power Button.
- Source
- HDMI
To take control of Samsung remote control use registAllKey() API.
Include in html file:
<object id='pluginAppCommon' classid='clsid:SAMSUNG-INFOLINK-APPCOMMON' style='visibility:hidden; position: absolute; width: 0px; height: 0px;'></object>
Include in javascript file:
var pluginObj = document.getElementById('pluginAppCommon');
pluginObj.registAllKey(); //register all keys inclucing Power Key
After this these keycodes could be added to javascript keydown event handler.
Use this code than recive to Source key,Power,HDMI code value.

The javascript application does not receive all keys pressed on the remote. Certain
keys on the remote (eg 36, 38 )are not passed to the web application. The FW
seems to be doing some kind of mapping before the keydown javascript event
handler receives the function. Is it possible to listen to all remote key
presses in javascript. ?
To register all the keys of remocon you can
use registAllKey API. By this you can get key codes of all keys.
This will register all keys of remocon including POWER key,
So you can unregister POWER key using unregistKey API.
Example:
var pluginObj = new Common.API.Plugin();
pluginObj.registAllKey(); //register all keys inclucing Power Key
pluginObj.unregistKey(tvKey.KEY_POWER); //unregister Power Key
pluginObj.unregistKey(tvKey.KEY_PANEL_POWER); //unregister Power Key
