What command to I need to bind to Drop the Briefcase?

A Steam Bug is preventing me from checking my own config file (for some reason my config.cfg gets overridden with nonsense when I close TF2) so I have to keep it on Read-Only, but that's not why I'm here today.

I would like to bind 'Drop the briefcase' to T, but there's no way I could try and find the line of code manually since 'Drop Briefcase' is unbound by default. Even on the Tf2 Wiki the command was described incorrectly or I have overlooked it. I've been searching the web for a good half hour.

What is the command line to bind "drop the briefcase"?

bind "t" "?????"

It's probably a really quick check for anyone who owns the game. For reference I am referring to the config file at this location:

C:\Program Files (x86)\Steam\steamapps\common\Team Fortress 2\tf\cfg\config.cfg

After going to the TF2 wiki and doing a quick search for useful commands, I was able to find that it is "dropitem." So a command would be bind "t" dropitem or whatever you want to do for the command.
