Recently I started tracking the time I spent on various coding activities using Org mode.
C-c C-x C-i is used to start the timer and
C-c C-x C-o is used to stop the timer. I like to add some details about where the time was spent when the timer is stopped. Org mode allows to enter such notes using
The description of this variable says -
Non-nil means record a note when clocking out of an item.
So I set the variable to true in my Org settings.
(setq org-log-note-clock-out t)
Now whenever I stop the timer, it opens a new buffer from where I can add a note describing what was done in that particular time.
My complete Org mode settings can be found here
