The Tools panel contains a number of tools for editing sequences in a Timeline panel. When you select a tool, the pointer changes shape according to the selection. For example, when you select the Razor tool and position the pointer over a clip in a Timeline panel, the icon changes to a razor . However, the Selection tool icon  may change to reflect the task currently being performed. In some cases, pressing a modifier key (such as Shift) as you use a tool changes its function, and its icon changes accordingly. Select tools from the Tools panel, or use a keyboard shortcut. You can resize the Tools panel and orient it vertically or horizontally.

Select any tool to activate it for use in a Timeline panel by clicking it or pressing its keyboard shortcut. Let the cursor hover over a tool to see its name and keyboard shortcut.

Selection Tool

The standard tool for selecting clips, menu items, and other objects in the user interface. It’s generally a good practice to select the Selection Tool as soon as you are done using any of the other, more specialized, tools.

Track Selection Tool

Select this tool to select all the clips to the right of the cursor in a sequence. To select a clip and all clips to the right in its own track click the clip. To select a clip and all clips to its right in all tracks, Shift-click the clip. Pressing Shift changes the Track Selection Tool into the Multi-track Selection Tool.

Ripple Edit Tool

Select this tool to trim the In or Out point of a clip in a Timeline. The Ripple Edit Tool closes gaps caused by the edit and cascades clips to the right or left in the Timeline in order to preserve all edits to the left or right of the trimmed clip.

Rolling Edit Tool

Select this tool to roll the edit point between two clips in a Timeline, simultaneously trimming the In point of one and the Out point of the other, while leaving the combined duration of the two unchanged.

Rate Stretch Tool
