I think it is necessary to create two checklist entries.

1st entry:

Source: `^. -ABC`  
Target: `ABC`  
Search mode: Regular Expressions  
PowerSearch: On.

This entry will find all segments that contain ABC in target but is missing in source and highlight ABC in target and the 1st character in source.

2nd entry:

Source: `ABC`  
Target: `ABC`  
Search mode: Simple  
PowerSearch: On.

This entry will find all segments that contain ABC in source and target. It will also highlight only ABC in source and target.

Regards,  
Oscar.
