I didn't find any documentation about that in anywhere. My personal setup which I use is prelude.
In the org-mode official documentation is pointed that:
Every item in a plain list1 (see Plain lists) can be made into a checkbox by starting it with the string
[ ]. This feature is similar toTODOitems (see TODO items), but is more lightweight. Checkboxes are not included in the global TODO list, so they are often great to split a task into a number of simple steps. Or you can use them in a shopping list. To toggle a checkbox, useC-c C-c, or use the mouse (thanks to Piotr Zielinski'sorg-mouse.el). Org-Mod Official Documentation Checkboxes
But on my setup this doesn't work, for any of mouse buttons (1, 2, 3). I expected that mouse-1 would work, but it doesn't toogle the checkboxes when I click it. Do I need to set some special keybinding? I see thatorg-mouse`is part of the standard extensions of Emacs... So I don't understand well how this works.
