Use the keyboard to navigate and adjust selected editing controls.
All help pages
Navigation
Use Tab and Shift + Tab to move between controls, and Enter or Space to activate buttons. In menus, use the arrow keys, Home and End to move; Escape closes the menu. A shortcut applies to the focused control, not to the entire editor.
Position and rotation
Focus a text, image or sticker move handle and use arrow keys to move by 1 pixel; hold Shift for 10 pixels. On a rotation handle, arrows rotate by 1° or 15° with Shift. Focus a sticker thumbnail and use Alt + Left or Right Arrow to change its layer order.
Timing
On overlay time ranges, arrow keys adjust by 0.1 seconds or 1 second with Shift. Home and End move toward the timeline boundaries. Use the focused handle to adjust an endpoint or move the whole range.
