javascript add to tinymce

Because I will forget unless I save a copy here.
This is a very basic function for adding a string to tinymce (I use it to add images that are listed elsewhere on a page).

// Adding content to the end of the tinymce editor
function addToTiny(newContent){
        var inst = tinyMCE;
        inst.execCommand('mceFocus',false,'content');
        inst.execCommand('mceInsertContent', true, newContent);
}

// Adding content to the end of the tinymce editor
function addToTiny(newContent){
	var inst = tinyMCE;
	inst.execCommand('mceFocus',false,'content');
	inst.execCommand('mceInsertContent', true, newContent);
}
