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.
