Yep - in fact it was your suggestion I think ...

Yes - not sure in which beta release this was implemented  but certainly
the version I have here supports it and this is from a few weeks back
... just checked it. You obviously need the BSC13 version of the X10
connector.  Actually the xAP Desktop faders send a 'toggle' command if
you click on the bulb icon  (although bulb 3 is setup differently by
default to hide the faders).

NB:  From with our experience of using BSC13 that in a xAPBSC.cmd
message to a LEVEL or TEXT device all parameters are optional although
at least one should be present or the command serves no purpose.  In
responses from devices ie xAPBSC.info or xAPBSC.event then all
paramaters are mandatory.  The specification is vague on this issue and
I need to add a clarification statement to the published version.

The reason for this is that you may not for example know in advance the
current LEVEL of a device when you wish to TOGGLE  its STATE - you
simply wish to turn it from ON to OFF or vv, so the requirement to
include LEVEL= is flawed, hence it is now optional. In a simple transmit
only device eg an on/off  lightswitch the switch could never know the
level anyway.
