You can find the collection toolbar below the row of tabs. If you have a high resolution monitor and the toolbar buttons are too small, turn on the "large toolbar icons" option in the Appearance Preferences. The buttons available on the collection toolbar depend on the active tab. Buttons that do not apply to the active tab are invisible. The order of the buttons is always the same. From left to right, the collection toolbar offers the following commands:
New Folder
New Clip
Duplicate Clips
Move Clips
Move Up
Move Down
Sort Alphabetically
Merge Clips
Split Clips
Delete Clips
Copy Clip to Clipboard
Paste as New Clip
Create Clip from Text File
Insert and Extract Text
Reformat Text
