DuckDuckGoRecord Mode is the single most common answer here. With it active, every property change on a selected element becomes a keyframe at the playhead. With it inactive, the same change updates the element across the entire timeline and creates nothing.
If one or more of these match what you are seeing, you are on the right page.
Ordered from most to least likely. Work down the list — each cause is paired with what to do about it.
Click the red record button in the transport controls or press Ctrl+Alt+R. Record Mode is activated automatically when Animate mode opens, unless Auto-keyframe Mode has been set to Manual in Preferences.
Press Ctrl+2 or click Animate in the mode switcher. Design mode has no timeline to record into.
Select the element first. Record Mode captures changes to selected elements only.
Press K to create a hold keyframe at the current value on all animated properties, or click the diamond icon next to a single property in the Properties Panel to keyframe just that one.
In Edit → Preferences under Animation Settings, set Auto-keyframe Mode to On by default so recording is active whenever Animate mode is open.
