Portaclip

Synergy is a cross-platform application that allows you to use the same mouse and keyboard on multiple Windows, Linux or MacOS devices. However, some may have problems with clipboard sharing, which is where this utility comes into play.

Portaclip is an open-source application that can send clipboard contents to another device on your network. It works best with Synergy, as it can transmit clipboard text based on mouse movement, but it also allows you to send the text manually.

It is not uncommon for OS updates to mess up certain things, and this is especially likely when dealing with a cross-platform program like Synergy. If clipboard sharing stops working for some reason, you can consider trying Portaclip.

All you need to do is launch the application on both of the systems you want to use, and then enter their IPs to enable a connection. The clipboard text is sent in the form of a UDP message in the UTF8 format.

If you are using Synergy, the application will detect when the mouse cursor has left the current monitor and send the text stored in the clipboard to the connected device automatically.

However, those who aren’t using Synergy can still take advantage of this application, as it is possible to force it to transmit what you have copied to the clipboard at any time. Of course, it would have been great it this could be done via hotkey, as the process isn’t particularly convenient.

If a few more features were added, Portaclip could be useful even for those who aren’t relying on Synergy to share keyboard and mouse input. As it stands, though, this application can only be recommended to users who are having issues with Synergy’s clipboard sharing feature.
