How long your talk is; the timer counts down from this. Any number of minutes, e.g. 20 or 7.5.
The new duration applies when the current timer is reset.
Off by default, so a presentation remote sending keys to this window can't change the timer.
A theme is a named set of styles. Choosing one replaces the styles below.
Each style starts at a number of minutes from zero: positive before, negative over time. The closest to zero applies.
Time moves left to right, until the timer stops an hour over. Widths are not to scale, and a // break marks a section cut short.
Settings couldn't be saved in this browser, so they will be lost on reload.
Or use $duration, the presentation duration, e.g. $duration / 10.
$duration
$duration / 10
Inactive applies whenever no other style does, so it has no start time.
Each effect starts a number of seconds after the style begins.
