Is there a way to have a computer on the network use hotkeys on their keyboard to toggle on/off WLED presets? Something like num1 starts preset 1, num2 starts preset 2, num0 turn off all LED’s?
I would expect that you could find a macro utility that could run HTTP calls from keys.
If you can create the URLs or CURL calls, you can script the actions by assigning the command to specific keyboard actions. Look for what @tonyno suggests - unless you have cmd scripting skills.
