Gestured to keep moving

WAVEDON

Think of how you might signal someone to continue walking past you.

"Gestured to keep moving" hints at a hand motion urging someone forward, which is often called "waving on." The answer combines "waved" (the gesture) with "on" (meaning continuing or moving), forming "WAVEDON." It’s a straightforward charade-style clue where the two parts merge to describe the action literally.
