How can I swap modifier keys?

Product: Synergy (all versions)
Operating system: Windows, macOS, and Linux

You might want to swap your modifier keys, based on what seems more convenient or comfortable to you.

For example, when sharing a Windows keyboard with a Mac, using the hotkey for copy ie. Command+C can be tricky because the Windows key is in a different place than the Command key on a Mac.

Follow the steps below to swap your modifier keys:

5. You will see a Screen Settings window.
6. On the right side you will see a vertical list of all the modifier keys.
7. You change the keys based on what you want which key to do (for example swap "Super" with "Ctrl" and "Ctrl" with "Super")
8. Click OK to close the Screen Settings window.
9. Then click OK again to close the Server Configuration window.
10. Click Apply to save your new configuration.

If the changes don't work as expected

Please note that making changes on the secondary/client computer changes the keys for that computer only. Opening the same window for the computer that is set to the primary/server computer will not swap the keys unless the primary/server computer becomes a secondary/client computer.

Once you have made the changes it can be helpful to open up the on-screen keyboard to see how the changes you have made are reflected on the client. On Windows, it's called the OnScreen Keyboard, and on macOS, it's called the Accessibility Keyboard.
