Control not working in iTerm 2 when using Programmer Dvorak keyboard layout

I'm using the Programmer Dvorak keyboard layout and found that the Control key does not work in iTerm 2. Emacs is unusable as a result, and I can't interrupt processes with Ctrl-C. Interestingly, the only thing I have found control to do is that Ctrl-Z still sends SIGTSTP.

I've swapped the Ctrl and Caps-Lock keys at the Mac level, but undoing that has no effect. I use zsh, but running bash doesn't help. Everything works fine in Terminal.

How can I get a working control key?

PS: Reverting back to QWERTY does fix this, but that's not really an option.

Solution 1:

Edit: There is now a new version of Programmer Dvorak that works with key combinations like ⌃A, so the instructions below are no longer needed.

◊ Option modifier is currently non-functional. Also, you cannot replace a default Roman layout with this one. Control keys should now be functional.

Option worked everywhere I tested, so non-functional could just mean that states under option don't output non-ASCII characters. If you want to disable all other input sources, you can edit the HIToolBox plist.

Instructions for older versions of Programmer Dvorak:

Open /Library/Keyboard Layouts/Programmer Dvorak.bundle/Contents/Resources/Programmer Dvorak.keylayout

And add this to modifierMap:

<keyMapSelect mapIndex="3">
  <modifier keys="control anyOption? anyShift?"/>
</keyMapSelect>

Add this to keyMapSet:

<keyMap index="3">
