Is there any way to have more than one realm active for bda? I have
several realms that I use and I use bma for some keystrokes and bda for
others, whose functions may change, i.e. start and stop recording of the
call.
I'm not aware of any way to have more than one realm active. In a nutshell you'll have to create some realms with overlapping functionality. You can probably use execute_extension creatively to cut down on the copy & paste. :)
