Hotkey shotcut for marking done (Ctrl+D) not working on Mac OSX 10.10.5

[sorenpeter]

When I try to use the CTRL+D to make a task as done, the box is not checked.
Instead it delete the next character (as Fn+Backspace on mac).

All other shotcuts works fine for me. but not the one for marking task as done

It seem to be a "feature" of OSX: https://support.apple.com/en-us/HT201236

I tried turning the system shotcut off by editing ~/Library/Preferences/com.apple.symbolichotkeys.plist
57 > (incl. 100=d and 262144 = Control) > set "enable" to "NO" reboot
but it did not help....

Any way to change the shotcut for the mac version of jdotxt to use Cmd (⌘) key instead of the Ctrl key?
