# Bi-Directional Text Marks

[LILT Translate](/kb/introduction-to-lilt-translate) supports right-to-left (RTL) and left-to-right (LTR) directional marks. These controls are used to determine the way adjacent characters are grouped with the respect to text direction.

As an example, let's look at the phrase: *"The language C++ is a programming language used..."*

When translating from English to Arabic without an LTR mark, the browser will render the phrase into this:

لغة ++C هي لغة برمجة تستخدم...

With an LTR entered inserted after *"C++"*, it will render as the writer intends:

لغة C++ هي لغة برمجة تستخدم...

This [video demo](https://lilt.wistia.com/medias/qamps918q6) in a previous version of LILT Translate further demonstrates how directional marks work.

Directional marks can be added into the target text field from the `Insert` tab. Add a mark directly after the word you want to set directionality on.

You can also insert marks by using the following keyboard shortcuts:
