Include this script in your Go present slides to make them right-to-left

rtl.html

<script>
document.addEventListener('DOMContentLoaded', function(){
	// Code is generally left-to-right, so we set all <pre> tags with dir=lrt explicitly.
	var pres = document.getElementsByTagName("pre");
	for (var i = 0; i < pres.length; i++) {
		pres[i].dir="ltr";
	}
	
	// Everything else is right-to-left.
	document.getElementsByTagName("body")[0].dir="rtl";
	
	// Add CSS rules to override the slide change animation direction
	var style = document.createElement("style");
	style.setAttribute("media", "screen");
	document.head.appendChild(style);
	style.sheet.insertRule(".slides > article.far-past{transform: translate(2040px) !important}");
	style.sheet.insertRule(".slides > article.past{transform: translate(1020px) !important}");
	style.sheet.insertRule(".slides > article.next{transform: translate(-1020px) !important}");
	style.sheet.insertRule(".slides > article.far-next{transform: translate(-2040px) !important}");
	style.sheet.insertRule(".slides.layout-widescreen > article.far-past, .slides.layout-faux-widescreen > article.far-past{transform: translate(2260px) !important}");
	style.sheet.insertRule(".slides.layout-widescreen > article.past, .slides.layout-faux-widescreen > article.past{transform: translate(1130px) !important}");
	style.sheet.insertRule(".slides.layout-widescreen > article.next, .slides.layout-faux-widescreen > article.next{transform: translate(-1130px) !important}");
