Directional text markers
Is there a standard term that includes both the left-to-right mark and the right-to-left mark? I can envision merging these pages, since they cover closely related concepts (in automobiling, both left-hand drive and right-hand drive are covered in Left- and right-hand traffic), but I don't know about a single term that could cover both, and putting both characters' full names into the title would be awkward. PS, after leaving this question I wondered if the section title might be a useful term, but the only Google hit for "directional text markers" is this thread, and "directional text marker" returned nothing useful.

 * The term would be directional formatting characters as seen in Bi-directional text. Though I would suggest keeping the pages separate, as it is confusing to read an article that covers opposite things. The situation is actually much more complex as can be seen in Template:Bidi Class (Unicode) which must be incorrectly applied in Unicode character property. These characters have a more general name of Bidi Control. Graeme Bartlett (talk) 03:35, 20 January 2019 (UTC)

Google images
Is there any way to configure Google images search results to only show grey and old images? I'm looking for notable Africans from the colonial era and wish to only get colonial era photographs. Thanks. 79.67.87.186 (talk) 20:28, 19 January 2019 (UTC)
 * They're called black and white and sepia toned photographs. Sleigh (talk) 00:30, 20 January 2019 (UTC)

If in the google images you click on tools, then colour, then black and white is a choice. It then has suggestions of 1800s, 19th century, 1930s. There is also a time range, but it does not seen to function. Perhaps Google is not recording when the photo was taken, but when it appeared on a web site. Note there was no photography in what I would call the colonial era. But I suppose that extended to 20th century in Africa. Graeme Bartlett (talk) 03:14, 20 January 2019 (UTC)
