We did some feature adding to the extension for compatibility with LibreMD. Originally we were unable to paste directly into the OnlyOffice plugin as it was running on a separate port but that has been fixed by the developers so we are adding an option called LibreMD compatibility.
In the meantime, you can use the compatibility mode to paste into the LibreMD EMR.
We also had to find some keypresses that work with LibreMD and have decided on Ctrl+Insert for Record and Alt+Insert for Shortcut Popup.
These keypresses are available in the Preferences dropdown menu and should also work with the OpenEMR and LibreEHR.
