Emacs: easily set timers with TMR

Protesilaos Stavrou demonstrates tmr, an Emacs package for setting and managing timers with descriptions, grid views, and notifications.

In this ~15-minute video I demonstrate a package of mine called "tmr" (pronounced as an acronym or as "timer"). It uses a simple notation to set the duration of a timer at the minibuffer prompt. Once the timer elapses, Emacs shows a notification. The desktop environment will also include one, as well as an audio alert (those are configurable). Timers can optionally have a description. They may also be listed in a tabulated/grid view, which makes it easier to work with them (to edit their description, reschedule them, etc.). Running timers may also be displayed on the mode line. The publication of this video is on my website, together with sample configuration: protesilaos.com/codelog/2026-01-19-emacs-timers-tmr-demo/
