In a normal reverse
synchronization flow, the user asks the viewer to synchronize the text editor with a given location in a given page of an output file, the viewer asks the SyncTEX parser for the input file name and line number corresponding to the location; it then asks the text editor to display the named input file and highlight the numbered line.
For reverse synchronization, the user asks the
viewer to synchronize the text editor with a given location in a given page of an output file, the viewer forwards this information to the synctex tool together with some scripting command to activate the text editor, the synctex tool transparently asks the SyncTEX parser for the input file name and line number corresponding to the information it has received, then it asks the text editor to proceed according to the received scripting command
