In the properties box that comes up, click on the "Shortcut" tab. There should be a "Target:" line in the box that contains the path to the MTW executable, something like this (from my machine):

"D:\Games\Total War\Medieval - Total War\Medieval_TW.exe" -strictserver

This is from a standard MTW-VI installation, so contains the "-strictserver" switch. To activate the "-ian" switch, add one space, then the switch (-ian), immediately after strictserver, and save the new properties.

Start a game normally, then when you want to change factions hit the function keys. That part I can't help you with - don't know which keys are linked to what factions. Just play around with a test session to figure it out.

Have fun!
