The Governing Council of the United Nations Development Programme began the observance in 1989, taking the date from Five Billion Day, 11 July 1987, when the world’s population was estimated to have crossed five billion; the United Nations Population Fund now leads the campaign.

The United Nations Educational, Scientific and Cultural Organization proclaimed the day in 1966, and it was first observed in 1967; UNESCO also leads International Mother Language Day on 21 February and World Teachers’ Day on 5 October.

The General Assembly declared the day in 2007 and set it on the birth anniversary of Mahatma Gandhi, so that the date honours the leader whose method of non-violent resistance the resolution names.

WHO became a specialised agency of the United Nations on 7 April 1948, and the first World Health Day was observed in 1950; the organisation announces a theme for the day each year and its headquarters are at Geneva.

The General Assembly adopted it on 10 December 1948 at Paris, and the observance of the anniversary began in 1950; the Declaration has thirty articles and is the most translated document in the world.

The General Assembly established the day after the Stockholm Conference on the Human Environment of 1972, and it has been observed since 1974 under the lead of the UN Environment Programme, with a different country hosting the main event each year.

The Print pane of PowerPoint offers handout layouts of 1, 2, 3, 4, 6 and 9 slides per page, so nine is the largest number, and the 3-slide layout is the one that leaves ruled lines beside the slides for the audience to write on.

A template stores the theme, masters, layouts and sample content that new presentations are started from, and its extension in the current format is.potx; the older format used.pot.

The slide master holds the formatting that every slide built on it inherits — title font, body font, bullet style, background, colour scheme and the position of a logo — so one edit there updates the whole deck.

Shift + F5 is the "play from here" key, and it saves a presenter from running through a long deck while checking one slide.

Animations act on the objects of a slide — text, shapes, pictures, charts, SmartArt — and fall into four groups: Entrance, Emphasis, Exit and Motion Paths.

A transition is the visual effect between two slides — Fade, Push, Wipe, Split or Morph — and its gallery, duration, sound and advance timing all sit on the Transitions tab.

It adds a fresh slide below the selected slide, using the layout of the current one.

It lays every slide of the deck side by side as a thumbnail, so a slide can be dragged to a new position, copied, hidden or deleted, and the flow of the whole presentation can be judged at a glance.
