# Clock, undo, saves

> Pause and speed the clock, undo and redo with the 30 second refund window, and how the game saves, exports and imports a Company.

`Space` pauses and resumes the clock, `S` changes its speed, `Z` undoes your last action, and the game saves your Company by itself every few seconds. While the clock is paused, you can still place, move, sell and resize, so use a pause to plan.

## Pause and speed

The toolbar at the top right holds the clock controls.

Look at the speed button. It shows the current speed, such as **1×**, and it lights up above 1×.

1. Press `Space`, or press **Pause (Space)** in the toolbar. The button turns into **Resume (Space)**, and the Board stops moving.
2. Press `Space` again to resume.
3. Press `S`, or press **Speed (S)**, to step to the next speed: **0.5×**, **1×**, **3×**, **10×**, then back to **0.5×**. Perks can add **20×** and **40×** to the cycle.

At 1× one second of play is one second of the clock. The calendar on the HUD runs faster: one second is one calendar minute. A faster speed runs more Steps in the same real time, and the Simulation gives the same answers at every speed, so use a high speed to wait and a low one to watch a failure.

### Pause on blur

When you switch to another tab or window, the game pauses by itself, and it resumes when you come back. This is the **Pause when the window loses focus** switch in **Settings**. It is on by default. If you pause by hand and then leave the window, the game stays paused when you return.

A second switch, **Pause on SEV1 and SEV2**, pauses the clock when a serious Incident starts. It is off by default.

## Undo and redo

Press `Z` to undo your last action. Press `Shift+Z` or `Y` to redo it. The toolbar buttons **Undo (Z)** and **Redo (Shift+Z)** appear after your first action, and dim when there is nothing to undo or redo. The change pill under the toolbar also carries an Undo icon after a change.

What you can undo: placing, selling, resizing, Links and cuts, Tidy, option changes and bulk actions. A toast says what happened, for example **Undid: Placed App Server.** or **Redid: Placed App Server.**

The history holds the last 50 actions. A new action clears the redo list.

### The 30 second refund window

An undo within 30 seconds of the action reverses its Cash exactly. Undo a purchase of $240 after 10 seconds and you get the $240 back. After 30 seconds the Cash settles at normal prices:

- Undoing a placement refunds half of the price, as a sale does.
- Undoing a sale costs the full place price again.
- Undoing a resize moves no Cash.

Timers are on the clock, so a paused game does not run the 30 seconds out.

Undo restores the Design, not the world. Credits, memory leaks and failures keep what time did to them. Undo never gives you more Cash than you paid.

Two refusals to know: **Nothing to undo.**, **Nothing to redo.**, and **Not enough Cash to undo that.** when the settled price is more than you hold.

## Autosave

The game saves the open Company every 5 seconds of clock time, and once at the moment you found it. It stores the file in the browser, on this device. A Company on a paused clock does not advance, so it does not save again. Sandboxes and Challenges do not save to a Company.

Because the save lives in the browser, clearing site data deletes it. Export a save for a Company you care about.

## Companies

The browser keeps any number of Companies. Open the title screen with **Menu (Esc)**, then **Title screen**, and choose **Companies**. The list shows every Company with its Venture, Era, users and play time, newest first, and marks the current one **Current**.

1. Select a Company.
2. Press **Continue** for the current one, or **Open company** for another.
3. To remove it, press **Delete company**, then **Delete forever**. **Keep company** cancels. Deleting also deletes its Design, and there is no undo.

## Export and import

1. On the Board, press `Esc`, choose **Settings**.
2. Press **Copy save as text**. The toast reads **Copied the save as text.** The clipboard holds one line that starts with `QSV1:`. Paste it into a file or a note.
3. To load it, open **Settings** and press **Import a save**. The browser asks **Paste a save (QSV1:…)**. Paste the line and confirm.

A good import ends with **Save imported.** and replaces the open Company with the file. The old state is gone, so export first if you want to keep it. Failures say why:

- **That is not a save.** The text is not a Quorum save.
- **That save is from another build (x; this build is y).** The game version differs.
- **That save could not be read.** The text is damaged.

A Sandbox or Challenge answers **A Sandbox or Challenge has no save.** to both buttons. **Copy state as JSON** in the same list copies the raw game state, for bug reports.

## Mistakes to avoid

- Waiting 30 seconds and expecting a full refund. After the window, an undo pays the settled price.
- Pressing `S` while a text field has focus. Keys are ignored inside fields.
- Importing over a Company you have not exported.
- Leaving a high speed on through an Incident. Press `S` or `Space` to slow down.
