Every figure in a Kepler answer is cited. A citation is the value itself, shown as colored, underlined text. The color tells you the kind of source: a filing, a transcript, a web page, or one of your own documents. ## Open a source Click a citation. The source opens in the side panel next to the chat, at the cited passage, with the passage highlighted. ![A cited value selected, with the matching value highlighted in Apple's 10-K alongside it](https://mintcdn.com/kepler-a6ccf6fc/RVsTkAHzK349hoa0/images/citation-source.png?fit=max\&auto=format\&n=RVsTkAHzK349hoa0\&q=85\&s=169a92d495b4df8df2b50f786b60bb40) * **Filings, transcripts, and decks** open on the exact page. * **Web pages** open in full, scrolled to the cited passage. A label tells you whether you are reading the full text or an excerpt. * **Spreadsheets** open as Excel shows them, on the cited cell, with the formula bar above the grid. To open a source as a full page in a new browser tab, hold ⌘ and click the citation. > [!TIP] > > Press \[ and ] to step through the citations in an answer. Press ⌘ F to search inside an open document. ## See how a number was calculated Some figures are calculated, such as a margin, a growth rate, or enterprise value. Click one and it opens as a small spreadsheet, with the formula in a formula bar and each input in its own cell. * Click **Show how … is computed** on a row to open the calculation behind that input. * Click **Open the source of …** to open the filing or document the input came from. The calculations run in code, so every input is one click from its source. ## See everything a chat read Open the side panel with ⌘ \\, or the panel button in the chat header. The **Context** tab shows: * **Plan:** the steps Kepler took to answer. * **Outputs:** the tables and workbooks it produced. * **Sources:** every filing, transcript, web page, and document it read. Sources you open stay as tabs in the panel, so you can move between them. This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
