On macOS 10.14 and later

Clipboard Manager simulates pressing the paste shortcut (Cmd+V), so the Paste Script is not needed.

On macOS 10.13 and earlier

Clipboard Manager calls the Paste Script that simulates pressing the paste shortcut (Cmd+V). Without the Paste Script, Clippboard Manager puts the items to the clipboard, but does not paste items to the current application (need press Cmd+V).

Create file:

Paste.applescript

in the scripts folder:

~/Library/Application Scripts/cz.jv.ClipboardManager

with content:

tell application "System Events" to keystroke "v" using command down
