# a) If ESC, escape without saving changes
# b) If left-click:
# i) Unlock (modify) ONLY the fiducial with matching index
# (need to get version for Slicer3 to determine list numbering)
# ii) Get fiducial under mouse and modify WITHOUT saving
# iii) call editSelectedFiducial
# c) If right-click:
# i) modify slice views (i.e. ignore)
# d) if RET, save new fiducial location
