In MediaWiki pages it is frequently required to write some text in a different languages, and possibly also with different directionality. For example, an quotation in English in an article in the Hebrew Wikipedia.
With the plain wikitext editor this can be achieved using HTML, for example <span lang="en" dir="ltr">. In some Wikipedias there are templates that do this.
There must be a way to do this using the VE GUI. For example, the user can select the text in a different language, open a dialog with "Language properties" and select "English language" and "Directionality: Left-to-right".
