This page is for everyone. Use it as a quick lookup when you meet an unfamiliar term anywhere in the docs — each entry is one short definition plus a link to the page that covers the topic in depth. Terms are listed A–Z. *** **Adaptive Card** — The notification card an expert receives in their Microsoft Teams chat when a worker invites them to a Remote Expert session, with a one-click **Join Meeting** button. See [Join a Remote Expert Session](/frontline/remote-expert/join-session). **Altoura Remote Expert (Teams app)** — The Microsoft Teams meeting extension the expert adds to a live meeting to annotate the worker's view and share files. See [Add the Remote Expert App](/frontline/remote-expert/add-teams-app). **Anchor gem** — A diamond-shaped spatial marker an author places for a step, linking that step to a precise physical location. A tethered line connects the step panel to the gem. See [Anchoring & QR Codes](/frontline/overview/concepts/anchoring-and-qr-codes). **Author Mode** — The mode for content creators: build tasks and steps, place 3D models and anchor gems, configure choice steps and completion criteria, and preview the operator experience. See [Author vs. Operator](/frontline/overview/concepts/author-vs-operator). **Choice step** — A step that presents selectable options, each wired to a destination step. The worker must pick one to continue — this is how procedures branch. See [Procedures, Tasks & Steps](/frontline/overview/concepts/procedures-tasks-steps). **Completion step** — The step that marks the end of a procedure path — the final step of a linear procedure or the end of a branch created by a choice step. See [Procedures, Tasks & Steps](/frontline/overview/concepts/procedures-tasks-steps). **Device pairing (PIN pairing)** — Signing a headset in without typing credentials: the device shows a 6-digit PIN, you enter it in the Procedures Portal, and your authenticated web session transfers to the device. See [Device Pairing](/frontline/procedures-portal/device-pairing). **Follow Me** — A panel behavior that keeps a supported panel positioned in front of you as you walk or turn. Toggled with the pin-shaped button in the panel's top-right corner; off by default. See [Follow Me in Operator Mode](/frontline/procedures/operator/follow-me). **Hand menu** — The contextual menu available during a Remote Expert session on the HMD via a palm-up gesture: mute, reposition the call panel, toggle the spatial mesh overlay, and exit. See [Remote Expert Hand Menu](/frontline/remote-expert/hand-menu). **Media panel** — The panel that shows a step's attached images, video, or audio alongside the step instructions. Appears only when the step has media. See [Media Panel in Operator Mode](/frontline/procedures/operator/media-panel). **Mode selection** — The dialog that appears after choosing a procedure, asking whether to enter as **Author** or **Operator**. Shown only to users with Author access. See [Author vs. Operator](/frontline/overview/concepts/author-vs-operator). **Operator Mode** — The execution-only mode for field workers: follow steps with AR overlays, view media and 3D content, and complete tasks — with no editing controls. See [Author vs. Operator](/frontline/overview/concepts/author-vs-operator). **Organization** — The scoping unit in the Procedures Portal. Each organization maintains its own independent set of procedures, and the selected organization determines what you see, create, and share. See [Procedures Landing Page](/frontline/procedures-portal/landing-page). **Procedure** — A digital, interactive, step-by-step work instruction, made of tasks and steps and enriched with media, 3D models, and anchors. See [Procedures, Tasks & Steps](/frontline/overview/concepts/procedures-tasks-steps). **Procedures Portal** — The browser-based workspace where procedures are created, organized, previewed, and published, and where devices are paired. See [Procedures Landing Page](/frontline/procedures-portal/landing-page). **QR anchor** — The printed Altoura Frontline QR code fixed at a work site. Authors and operators scan the same QR at the same location so all content appears exactly where it was placed. See [Anchoring & QR Codes](/frontline/overview/concepts/anchoring-and-qr-codes). **Remote Expert** — The live, see-what-I-see assistance capability: the worker starts a session from their device, the expert joins from Microsoft Teams and guides them with anchored annotations and shared files. See [How Remote Expert Works](/frontline/remote-expert/how-it-works). **Rescan** — Re-scanning the QR code to re-anchor a procedure when placed content looks off-position. All placed items reposition with the updated anchor, preserving the author's relative placement. See [Anchoring & QR Codes](/frontline/overview/concepts/anchoring-and-qr-codes). **Run Mode (Web)** — A read-only preview in the Procedures Portal showing how a procedure will execute, without allowing edits. See [Run Mode (Web)](/frontline/procedures-portal/run-mode). **Spatial mesh** — A wireframe overlay drawn over the surfaces the device has mapped. Toggled from the Remote Expert hand menu or by voice ("Show mesh" / "Hide mesh"). See [Remote Expert Hand Menu](/frontline/remote-expert/hand-menu). **Step** — An individual action within a task, performed in sequence. Each step can carry its own description, media, 3D content, and anchor gem. See [Procedures, Tasks & Steps](/frontline/overview/concepts/procedures-tasks-steps). **Step Main Panel** — The always-visible panel during a procedure showing the step number, task title, description, navigation controls, step list access, and the tether indicator when a gem is configured. See [Procedure Panel View in Operator Mode](/frontline/procedures/operator/panel-view). **Task** — A high-level grouping of related steps within a procedure — for example, *Prepare Equipment* or *Replace Filter*. See [Procedures, Tasks & Steps](/frontline/overview/concepts/procedures-tasks-steps). **Task list** — The view of a procedure's full task and step structure, used to see progress and navigate directly to a step. See [Task List in Operator Mode](/frontline/procedures/operator/task-list). **Tether (thread)** — The visible line connecting a step panel to its anchor gem in the physical environment. It updates dynamically as the worker moves and appears only for steps that have a gem. See [Anchoring & QR Codes](/frontline/overview/concepts/anchoring-and-qr-codes). **3D Model Panel** — The authoring panel for browsing the asset library and attaching 3D models to a step. See [3D Model Panel in Author Mode](/frontline/procedures/author/3d-model-panel). **Voice commands** — Hands-free phrases that trigger actions on the HMD, such as navigation and the spatial mesh toggle. See [Voice Commands](/frontline/hololens/reference/voice-commands). *** Next: see where each capability runs in [Platforms & Devices](/frontline/overview/platforms).
