How to use the PDF viewer — search, zoom, rotate, viewer modes, risk highlights, annotations, page navigation, and disclosure bundles

Written by Paul Gaston GOURON

The PDF viewer is the most capable preview mode in Emma. It renders documents as a continuous vertical scroll (all pages in one stream), overlays AI and manual risk annotations, and provides tools for search, navigation, and on-page collaboration.

For a general introduction to the viewer layout, see Document viewer overview.

Toolbar layout

Two floating toolbars sit at the bottom centre of the file panel:

Toolbar

Controls

Viewer mode (left)

Switch between Select text, Flag/select risks, and Comment modes

PDF tools (centre)

Zoom, rotate, search, and download

Page indicator (right)

Current page / total pages, with jump-to-page

Zoom and rotate

Zoom

  • Click Zoom out (−) or Zoom in (+) in the PDF toolbar

  • Keyboard shortcuts: to zoom out, + or = to zoom in

  • Zoom range: 20% to 150%. The current percentage is shown between the buttons.

Rotate

  • Click the Rotate button to rotate the entire document 90° clockwise

  • Rotation is remembered per file for the duration of your browser session

Some scanned PDFs have pages with different internal orientations. Emma detects per-page rotation and applies it automatically so text and highlights align correctly.

Search

Full-text search is available for single PDF files (not for merged disclosure bundles — see Bundles below).

  1. Click the Search icon in the PDF toolbar, or press F

  2. Type your query — results update as you type

  3. Use Next (Enter) and Previous (Shift + Enter) to move between matches

  4. The viewer scrolls each match into view and highlights it on the page

  5. The counter shows your position, e.g. 3/12 for the third of twelve matches

  6. Press Escape or click Clear to close search

Search is disabled while a comment pin popover is open, and the document dialog will not close on Escape until search is dismissed first.

When search is unavailable (bundle mode or a PDF without a searchable text layer), a warning icon appears next to the page indicator.

Page navigation

Continuous scroll — scroll through all pages naturally. Large documents (50+ pages) load pages incrementally as you scroll for performance.

Page indicator — the current / total badge at the bottom right always reflects the page closest to the centre of your viewport.

Jump to page — click the page indicator to open a popover, enter a page number, and press Enter. The viewer scrolls directly to that page.

Jump from sidebar — selecting a risk, key term, signature page, or comment in the Document Review sidebar scrolls the PDF to the linked location and highlights the relevant area.

Viewer modes

Three modes control what happens when you interact with the PDF. Switch modes using the left toolbar or keyboard shortcuts:

Mode

Shortcut

Icon

What it does

Flag / Select risks

R

Shield

Draw bounding boxes to flag new risks or select existing annotation areas

Select text

S

Pointer

Select text on the page (available when the PDF has a text layer)

Comment

C

Message

Click anywhere on a page to pin a new comment thread

The active mode is highlighted with a coloured label. Select text mode is hidden automatically for PDFs without a searchable text layer (scanned images only).

Risk highlights and annotations

Risk-related content appears as coloured overlays on the PDF:

Overlay type

Appearance

Source

AI / check findings

Coloured box matching risk level (High, Medium, Low, etc.)

Automated checks run against the document

Manual bounding boxes

Blue dotted outline

Drawn by a reviewer in Flag/select risks mode

Selected highlight

Stronger outline / fill

Currently selected risk or key-term reference

Colour coding by risk level:

Level

Typical colour

High

Red

Medium

Orange / amber

Low

Yellow

Unspecified

Grey

No risk

Green (usually not shown as an overlay)

Viewing an existing risk

  1. Click a coloured highlight on the PDF, or click a finding in the Risks tab

  2. The sidebar switches to the Risks tab with that finding expanded

  3. The PDF scrolls to all bounding boxes linked to that finding

  4. Use the previous / next reference controls in the sidebar when a finding spans multiple locations

Creating a manual risk (bounding box)

  1. Switch to Flag / Select risks mode (R)

  2. Click and drag on the PDF to draw a rectangle around the relevant clause or passage

  3. The Add finding dialog opens automatically

  4. Fill in:

    • Topic — the thematic area (e.g. Employment, IP)

    • Title — the check this finding relates to (select an existing check or create a new one)

    • Risk level — High, Medium, Low, Unspecified, or No risk

    • Summary — describe what you found and why it matters

  5. Click Save

The bounding box is linked to the finding and appears in the Risks tab, the Matrix, and the Red Flag Report.

If a check already has a finding for this document, Emma merges your new bounding box into the existing answer rather than creating a duplicate.

Editing or deleting a risk

  • From the Risks tab: click the pencil icon on a finding to reopen the dialog with existing bounding boxes, or edit the summary inline

  • From the PDF: click an existing highlight, then edit via the sidebar or dialog

  • Use Delete in the risk dialog or the delete button on a finding row to remove it

Hiding risk levels on the PDF

In the Risks tab, each risk-level group has an eye icon. Click it to hide or show all highlights of that level on the PDF without removing the findings from the sidebar. This is useful when reviewing High risks first and temporarily hiding Medium or Low overlays.

Comments on the PDF

In Comment mode (C):

  1. Click anywhere on a page to place a comment pin

  2. A popover opens where you type your message

  3. Use @ to mention a data-room team member — they receive a notification

  4. Submit to create the thread; the pin stays visible on the page

Click an existing pin to open the thread, reply, resolve, or delete it. Active threads are also listed in the Comments tab.

While a comment pin popover is open, keyboard shortcuts for document navigation are paused so you do not accidentally change documents.

Download

Click the Download button in the PDF toolbar to save the file. When an original (pre-conversion) version exists — for example a Word file converted to PDF for preview — Emma downloads the original format rather than the preview PDF.

Disclosure bundles

When a document is the main file in a disclosure bundle and all annexes are PDFs, Emma merges them into a virtual bundle PDF — one continuous scroll through the main document followed by each annex in order.

Bundle behaviour:

  • Divider labels appear at the start of each document in the bundle showing the file name

  • Page numbers in the indicator reflect the merged total across all files

  • Risk highlights and comments from annexes appear at the correct merged page offsets

  • Clicking a finding in an annex scrolls to the right position in the merged view

  • Full-text search is disabled in bundle mode (search each file individually by opening the annex)

Opening an annex URL directly redirects to the main bundle document so you always review the complete package.

Manage bundle membership from the Bundle section in the Info tab.

Tips for effective PDF review

  • Start with the Risks tab to see what Emma flagged, then click each finding to read the source in context

  • Use hide/show on risk-level groups to reduce visual noise on dense documents

  • Draw tight bounding boxes around the exact clause — this makes exports to the Red Flag Report and Excel more precise

  • For long agreements, use search to jump to defined terms like "Indemnity", "Termination", or party names

  • When reviewing signature pages, use the Signature review section in the Info tab to jump between signature locations quickly
