xfce4-clipman 2:1.4.4-1 (armhf binary) in ubuntu groovy

 Clipman enables you to store and recall X selections, as well as GTK+
 clipboard content. You can also define actions to be triggered by selecting
 some text pattern.
 .
 This package uses Xfce libraries but can be used without the Xfce panel
 and only requires a system tray (notification area).
