Yes, you can perform this remapping under Mac icon > “System Preferences” > “Keyboard” > “Modifier Keys…”
Ensure that you have selected the keys remapping to apply to the TrickleStar Advanced Keyboard at the “Select Keyboard” field.
When remapping the “Command” key, you are advised to remap the “Alt Opt” key as well. In general, it is advisable to swap both keys, i.e. the Command functionality bound to the “Alt Opt” key, and the Alt Opt functionality bound to the “Command” key.
Doing this would preserve the Advanced Keyboard’s ability to instruct the Mac to enter sleep mode, as both “Command” and “Alt Opt” keys are used in the process.
