I think I figured it out. The key is matching with Ctrl but in the plugins help file it refers to the button as "Control". If I just change "Control" in the plugin parameters to "Ctrl" it appears to be working right again. Alternatively, I can just change 'ctrl' to 'control' on line 256 of your plugin and it will use the correct symbol/key used in the plugin's help file. I appreciate your quick response(s)!
