Hi Yutaka,

I rewrote my function to this:

function toggleLineNum() {

	    var cfg = document.Config;

	    var isLineNumOn = document.Config.General.ShowLineNumbers;

	    document.Config.General.ShowLineNumbers = !isLineNumOn;

	    cfg.Save();

	}

but it still does not work… :-(

Hi ToadLoadin,

This is a frequently asked question. Please use Save() when you finished settings:

	cfg = document.Config;

	/// do something

	cfg.Save();

	

Of course, you can use the EmEditor command “Line Number”, and there is a toolbar button for this command.
