Click Parameters to Highlight Packet

In the latest versions, you can directly see which bytes from a TM packet were used to extract the value of the parameter
In the TM packet viewer, expand the Properties, and Raw data displays, and expand the Parameters tree to see the list of parameters from a specific packet. If you click on a parameter, the bytes of the TM packet where this parameter came from are highlighted.

If the parameter came from a whole number of bytes, the bytes are dark-shaded, if the parameter came from only a few bits of these bytes in the TM packet, then they are light-shaded.
