Unfortunately I realized I often do bad things like typing 'Y' with my left hand or other cross-overs. Once upon a time I got really into ergonomics and thought I wanted a split-keyboard. So now only using Karabiner-Elements, my settings are: I installed Karabiner-Elements and with no modifications other than running it got-back my "default" function from the original Karabiner of having the modifiers work again. While looking about that I found that Seil has since been deprecated and its git site now points you to Karabiner-Elements.

I didn't know a good place to shove this - but now in 2020 (my previous update to this page was from Jan 2016) and running MacOS Catalina 10.15.5 my Karabiner settings below ceased to allow me to use a modified (e.g., "shift") on my left keyboard and get a capital key from pressing the other key ("m") on my right keyboard.
