Direct Paste & Paste Helper
When you double-click on a history item in the timeline, it is copied to your clipboard again and you can use it by pasting to any application with ⌘ CmdV manually. Direct Paste, as the name suggests, allows you to paste selected snippets directly to other applications. You can enable this feature on Preferences -> General.
If you purchased Paste from the Mac App Store or use it from Setapp, you'll need to install Paste Helper in order to enable this feature. You don't need to install Paste Helper if you purchased Paste on our website.
