Google and some other developers have introduced us to what some have called the
hamburger menu button and now the 3 vertical dots button or vertical ellipsis. 
What is the official name of these buttons/icons?

It would be nice if developers could consistently use a particular icon for menus.
It would also be nice to know what to tell novice users to press.

**Background Info:**

Horizontal Ellipsis … `&#8230; &#x2026; &hellip;`

Apple uses the horizontal ellipsis and calls it the 
[More Options](https://support.apple.com/en-us/HT204839) icon.

According to <https://design.google.com/icons/> the icon is called "more horiz".

Vertical Ellipsis ⋮ `&#8942; &#x22EE; &vellip;`

Google+ for desktop seems to use this as a menu for communities. The Google+ app
uses this icon as a standard menu icon.

According to <https://design.google.com/icons/> the icon is called "more vert".

Identical To ≡ `&#8801; &#x2261; &equiv;`

Google Chrome uses an image similar to Identical To and calls it the 
[Chrome menu](https://support.google.com/chrome/answer/95414?hl=en).

It has also been called the "hamburger" icon, "hotdog" icon, Options menu, Menu button,
Overflow menu, Side menu, Menu drawer...

According to <https://design.google.com/icons/> the icon is called "menu".
