default.in icontains the following:
MENU_LOCK "DIK_1 & DIK_2"
LAUNCH_GAME "DIK_1"
LAUNCH_GAME_WITH_OPTIONS1 "DIK_LCONTROL & DIK_1"
LAUNCH_GAME_WITH_OPTIONS2 "DIK_LALT & DIK_1"
I thought that meant that to lock the menu you needed to depress both 1 and 2, to launch game with options 1 you need to press left control and 1, etc...
This doesn't appear to work though, left control by itself launches the game, and I can't figure out how to lock the menu
