I have a Kinesis Freestyle Pro but it came with a US layout for the keyboard and I wanted a UK one. The issue I’ve had is that not all the keys of an ISO UK keyboard fit/map on the standard ANSI layout, for example the # and ~ on the ISO sit next to the enter key but there is no key for this on the ANSI layout and I use a UK layout (eg. the £ is on the 3 key in the number row). This means that I can’t access the missing keys when I use a UK keyboard layout on my OS and I don’t want to use a US layout because my laptop keyboard which I often use is UK.
