I’m going to assume you’re on a Mac. Probably a M1. Press Fn key with the F2 to get function key behavior. You can also go to apple key->system settings->keyboard->keyboard shortcuts and change it to function keys. Then you won’t need to press Fn key. If you’re not on the M1, but still a Mac then you may not have the Fn key and just have to go to the settings and switch it to function keys. If you’re using Linux then I would need to know the distro and desktop environment. For example the Buffy the Vampire Slayer distro uses to start/stop animated desktop and can be turned off by right clicking desktop->display->hotkey tab-> then choose disable animated desktop or change the hotkey to something else.
