The text only feature is available on some publications at the publishers request. If you see a black box at the bottom of the page that says “Text”, this means that this article can be read in an easy, text-only mode (without images). Tap the black box. If there is only one article you will automatically get a text-only version of that article, however, should there be multiple articles you will be prompted to chose the article you wish to read.
To go back to the full publication page, simply tap on the black “Page” option at the bottom of the text.
It is possible to share a text only article via email by selecting the envelope icon (when available)
Furthermore you can increase or decrease the text size. There is also the option to select copy and paste text articles.
