Just the "/" shortcut to spin (yaw) the listener.

There are no listener Mod functions - the Mod functionality is 
admittedly pretty minimal - modifiers were added as needed...  If one 
wanted to add ModLstPosition(), srapi_xml.cpp would be the place to start.

See the SLABScape file scapemod.cpp - the "/" shortcut is implemented 
there.  That seems the natural place to add what you're after...

The slabtools do not presently fully support converting CIPIC HRTF 
databases to slab3d HRTF databases.  The CIPIC-related tools that exist 
were primarily implemented to examine CIPIC data.  We've experimented a 
bit with conversion but do not have anything release-ready.  The main 
steps prior to mat2slab() would be converting the HRIRs to minimum 
phase, converting the coordinate system from CIPIC coords to slab3d 
coords, generating the appropriate fixed-increment slab3d database grid, 
and generating or converting the ITDs.
