Then do this:
1) Run the program, then exit.
2) cd ~/Library/Preferences
3) cp net.sourceforge.iTerm.plist net.sourceforge.iTerm.plist.bak
4) plutil -convert xml1 net.sourceforge.iTerm.plist
5) edit the plist file, and find this section:
<key>Global Profile</key>
<string>Yes</string>
<key>Key Mappings</key>
<dict>
6) Insert the following after the <dict> (I wrote this with an Emacs macro after doing the first three by hand in the keyboard profile editor...) :
