modifier key mapping (without the modified key)

In Flirc and flirc_util it's not possible (yet) to record just the Left Ctrl key on its own. That is most useful, for example in Android Keymapper, to have a modifier key on the remote. (Kind of like a sticky Ctrl key.) Come to think of it, I've searched for 'modifier key' in the forum, but it's probably an existing topic. Cheers!

I may have used this command correctly to do just that:
sudo ./flirc_util record_api 1 165

The '1' is the Left Ctrl modifier key, and the '165' is the Left Ctrl key in the 'IEEE HID' list. (Found in Whole world Google but also attached for your reference. As used by Flirc.)

By the way it has to be said; the shipping company FedEx knew quite late about the import taxes into another country, they could have found out sooner, to avoid them being surprised. Like paying an exit fee. So they got that part back. (Thanks for the Skip 1s, no regrets:)
