The XPS 15-9530 keyboard requires that you hold the Function key to do home/end (Function+Left is Home and Function+Right is End). That works fine, but I have found that if Ctrl+Home and Ctrl+End are a bit finicky. Specifically, the key order I have to press to do a Ctrl+Home is Ctrl then Function then Left. If I do Function then Ctrl then Left, it only sends a Home and not a Ctrl+Home. Is there any way to work around this? It's a bit annoying to have my Ctrl+Home and Ctrl+End fail so often while I'm retraining myself.
