Correct. Additionally check FCOM PRO-ABN-ABN-00 "B: PROCEDURE LAYOUT" - PROCEDURE TITLE. You will see there are procedures either on ECAM or in the QRH. Knowing which ABNs are to be found inside QRH is a required skill for the black belt.
And not only those: Being acclimatized to using the paper form on the line and quickly flip pages to find the tables I was looking for visually, I have recently quite embarrassed yours truly with being unable to locate the Fuel Penalty Factors inside PDF on an iPad.
Imagine, on non ECAM aeroplanes it was by order of magnitude worse. If you did not know a NNC such as "Gear Lever Would not Move Up after Take-off" even existed be assured it is very hard to execute it in timely manner ;-)
