[. . . ] This switch of device continues until there is either another device assignment key Z_Devn, permanent or temporary, or the macro terminates, or the temporary assignment is explicitly cancelled. Cancellation is performed by the key X_CANCEL, which is the 73rd device reassignment key mentioned in section 5. Note that in a nested macro the temporary device switch continues until the entire macro ends, even if the X_DEVn key is in an inner macro. As an example, suppose I want to put a macro on key A that turns on both the current device and Device 1, which is set as the TV. Then either of the following macros will achieve this: A = Power, X_DEV1, Power or A = X_DEV1, Power, X_CANCEL, Power. Repeated pressing of Brightness+ cycles through a number of preset picture settings. The 16:9 button opens a list of various aspect ratio settings that you need to scroll through with the TV navigation pad Up and Down buttons and then press OK on the desired one. I have therefore created key moves for Device 1 on the Colour+/- and Brightness- buttons that map to Device 1 Up, Down and OK. When any device is selected I can now press 16:9 to open the aspect ratio list on the TV, then Magic followed by Volume+/- (i. e. I have achieved this with the macro Shift/16:9 = X_DEV1, 16:9, T-Shift. The first two macro keys open the aspect ratio list on the TV, but on their own they would leave Volume+/- and Channel- performing their volume and channel actions. The T-Shift turns them into Colour+/- and Brightness-, which are in the Aspect grouping and so operate Device 1 and which in turn pick up the key moves assigned to these keys to perform the required scrolling and OK actions. 9. The Light button To me, the behaviour of the Light button in the unextended device is the most irritating feature of the URC-7781. When you press any button, the backlight comes on and remains on for about 7 seconds. The only way to turn the light back on now is to press the Light button again!Well, the backlight behaves as though there are two switches between the light and its power source. Like any other button it turns the timeswitch back on but it also turns the toggle off ­ and groan, still no light, not until you press Light again to turn the toggle back on!The Light button performs this toggle action regardless of the reason that you are pressing it, and since it is also the Escape key in long Magic keypress setup operations this is, to say the least, irritating. 14 The Light key still has an Escape action in the extender, as described in section 7. 4, but when it is pressed as an Escape key it has no effect on the backlight. Instead it gives two flashes of the LED to show that it has performed an Escape action. Also, if it is pressed when the backlight is off but the toggle is on then it does not toggle the toggle switch. Bingo, the Light button does what you expect ­ when the light times out and you press the Light button, the light comes on!One further feature of the Light button is that when it toggles the toggle switch, but not otherwise, the keystroke gets passed through for key processing. [. . . ] You can use Delete Key Macro to delete from every key in turn, but it is better if you are prepared to examine the relevant memory area as displayed under the Raw Data tab of IR. exe. If you do this, you can assure yourself that nothing has got through the net that can potentially cause trouble later on. To do this, or to understand the issues in more detail, you need to know the basic format of these features. They share a common format, namely a 3-byte header followed by a body of variable length.
