tjohnston,
Many thanks for the response and sorry for the delay in replying (had login issues).
I have found out that a Key Binding can call a script as follows:
Bindings("Schematic").AddKeyBinding "F2", "run D:\Projects\scripts\viewdraw\hierarchy_bit_attr_visib.vbs", cmd, Key
But still don't know if such a script could be called from a Mouse Stroke
