Hi r2d3 - from what I can see there it looks like you've somehow pasted a gigantic amount of text (something the contents of an HTML file) into the keyboard shortcut in the Options dialog.

You need to just have the text: UnwrapCurve in the "command" part of the shortcut key, you will need to erase whatever huge chunk of text that's currently in there (try clicking in there and using Cmd+A or Ctrl+A to select all and then delete) and just put UnwrapCurve in instead.

Maybe this will happen if you right-click on the UnwrapCurve.htm file and then try to right-click and use "Copy" from that... ? It's ending up copying some huge bookmark and not just the basic text name.

Try just typing it in directly: UnwrapCurve rather than using copy/paste.
