Train travel geeks I need help

When booking London to France I’ve often used a hack where you enter a London station name (that I now can’t remember) after getting advice from maninseat61. I’ve googled it and can’t find it. Anyone know what it is? Instead of putting London St Pancras you put the name of this station and it comes in cheaper. Something like “London central” but I can’t remember
