Thank you for your reply 3FG!

I have two other questions and would appreciate if you could help:

1) In another Forum (www.bitwisecontrols.com) they suggested me to suppress the toggle bit.
I would like to try it before start setting up a macro for each button.
Is it possible to identify wich portion of the code (xxxx xxxx) corresponds to the toggle bit?

2) Is it possible to concatenate two IR signals in the same command, without a macro? (for example: xxxxxxxxxxx ; xxxxxxxxxxx)
Sorry if it is a too basic question! I am new in this area.

Thank you.
