Setting an item as context
To set an individual item as context, just right-click it, or select the item withCtrl+click. You can then choose to Add to Assistant context which adds it to whatever is the current context – you can add multiple things progressively in this way.
Or you can choose Ask about item and the item becomes the only thing in the Assistant’s context. Good if you want to have a focused discussion.
If you activate the Assistant when an item is opened, it is immediately available to the Assistant context (or is likely even already set). If so, you can click the toggle to add/exclude from current context.
Setting a selection as context
When you select multiple items in Fabric (by dragging, or holdingCmd /Ctrl and clicking), the floating bar will offer options for adding the selection to the Assistant context, or you can also access the Ask AI options by right-clicking any of your selected items.
