Not all of them, just some. For example, I use skip instead of ff. So, I reassigned << and >> to skip forward and skip backwards. They were reversed. To get skip forwards, I has to assign skip backwards to >> and vice versa.
The Red button did not do the red button activity. One place it is used is to delete a recording. It performed the Exit function which is also necessary but was not on another key that I could tell.
There are too few hard buttons on the X1.
