It's a reference rather than a copy, so updating the source, like your registered address, updates every document that uses it. A document's Document Management block showing highlighted placeholder chips for organisation, document ID and effective date ## Insert a placeholder Type `@` in the editor and pick a placeholder from the list. It shows highlighted while you edit. The placeholder list open below a paragraph, with General and Company Information groups ## Cross-reference another document To link another document by name, like your privacy notice, type `@document` and pick *Document*. The link survives renames and new versions. The @ menu filtered to "document", with the Document option under General highlighted ## Configure a live table For what a live table shows, see [Live tables](/documents/default-placeholders#live-tables). The Edit Live Document Version History panel with the Columns, Appearance and Filters tabs highlighted Click a live table to configure it. For a *Hazard Log Summary*, for example, **Filters** sets which hazards it includes, and **Filter by Risk Level** keeps only those with an undesirable initial or residual risk. The Edit Live Hazard Log Summary panel with Undesirable residual risk switched on and a filtered preview of five hazards * **Preview:** it shows the first 5 matching rows. * **Scope:** changes apply to this table only, unless you switch on *Apply to all instances* to change every copy. * **Case reports:** [the live hazard log table](/clinical-safety/clinical-documentation#the-live-hazard-log-table) covers using a *Hazard Log Summary* in a clinical safety case report. ## Create a custom placeholder When the defaults don't cover a value you repeat, define your own, like "Team responsible for onboarding" with the value "HR department". In the editor, open **Settings** → **Placeholders**. Click **Add Placeholder** to open *Create Custom Placeholder*. The Placeholder Settings panel with the Custom Placeholders and Default Placeholders sections highlighted Give it a label, pick a colour, choose a *Placeholder Type* and enter its value. Add a description if you like. The Create Custom Placeholder dialog with the Placeholder Type dropdown open **Pastable and Synced can't be swapped later without redoing every insertion.** * *Pastable* becomes ordinary text in each document. Use it for a standard clause each document adapts. * *Synced* stays live and updates everywhere. Use it when every copy must stay identical. **What we recommend** Use a custom placeholder for any value that appears in more than 2 documents and might change, like a product name. ## Related articles Where you insert placeholders, and everything else about writing a document.
