# A block's actions and its derived progress

Every block can carry a list of actions to do — a task's own "comments". As soon as a block has at least one action, its progress is no longer a value you set by hand: it's **derived** from how many actions are done.

## Opening a block's actions

**Right-click a block › Actions…** (shortcut **A** once the block is selected) opens the **Actions** tab in the right-hand panel. The block's title and its progress ("*n*/*total* · *percentage*%") show at the top, with a **Kanban** / **List** display choice.

## Adding, moving, completing an action

At the bottom of the panel, the **Add an action…** field creates a new "to do" action. Each action carries:

- a title,
- an **Owner** menu for who's responsible (yourself, or a free-text name),
- **Context** — a lightweight-Markdown text field (bold, italic, links) to spell out the task,
- its status buttons.

In **Kanban** view, three columns — **TO DO**, **DOING**, **DONE** — with, on each card, buttons to move forward (**Start**, **Complete**) or back (**Reopen**). In **List** view, each action is a line to check off, with the same Owner menu and the same **Context** link.

## Derived progress

From the first action added, the block's progress (shown in the grid and on the block itself) becomes *actions done / total actions* and stops being editable by hand — the manual progress field closes. Deleting the last action gives the block back a free progress value, editable directly again.

## What happens when you get it wrong

- **A status changed by mistake**: click the reverse button (**Reopen** after **Complete**, for instance) — every status change is also a command in the journal, undone by **Ctrl+Z**.
- **An action deleted by mistake when it was the block's only one**: progress becomes free again; **Ctrl+Z** brings back the action and the derived progress in one go.

- **A "Progress" column in the left panel**: a separate computed column, see *[The grid and columns](/docs/en/guides/grille-et-colonnes/)*.
- **Commenting on a block** (a discussion, not a task to check off): see *[Comment threads](/docs/en/guides/fils-de-commentaires/)*.
