I used Karabiner-Elements to remap F4 to Alfred 5 You need to change karabiner.json, the file is located in the config folder of Karabiner Elements. I used Visual Studio Code but I think most Text editors will do. Open karabiner.json Search for "spotlight" Replace "apple_vendor_keyboard_key_code": "spotlight" with "shell_command": "open -a 'Alfred 5.app'" Depending on the number of keyboard-profiles you have in Karabiner Elements you need to do it for every keyboard-profile. File, Save Restart Karabiner The mapping for F4 should look like this. Note that I changed F5 and F6 too but that's not relevant to this topic)
