How do I add a hotkey to restart the connection?

Written for Synergy 3 (v3.7.2) and Synergy 1 (v1.21.4), checked 3 October 2026.

Add a hotkey that restarts the connection when you need a quick reset, for example:

• If you have an error, such as the clipboard not syncing
• You often change monitor layouts, which need a restart to take effect

On Linux, hotkeys may not work yet if the server computer uses Wayland. More details: Hotkeys not working on Wayland
