Hi everyone, I probably sound a tad silly here but I am new to all of this and just trying to do it for my partner. I have everything installed but cannot figure out how to actually get or freeze the keys for the life of me. I have been unable to find any information that I really understood anywhere either. Could someone please explain how it works in depth? I can see the red cog where all the searches are but its a bit overwhelming at the moment.
