Ctrl & Fn keys
On most (if not all) recent Lenovo Thinkpads, it is possible to swap logical layout of the Ctrl and Fn keys in BIOS.
Enter the BIOS setup, then
config -> keyboard/mouse -> Fn and Ctrl Key swap
save and exit.
For really old farts like me this still does not put the Ctrl key in the right place. The correct place is, of course*, immediately to the left of the 'A' key, which is normally the Caps Lock key these days. Quite why such a little used function gets so much keyboard real-estate is a mystery to me - and for anyone used to navigating software with control-codes.
*The correct place is generally wherever you first learned it. People get quite impassioned over this, but I don't want to get into a holy war over it. What would be nice is if hardware/firmware suppliers gave people the option of easily choosing their preferred layout, as Lenovo do in their Thinkpad range, but extended it into allowing easy remapping** so that I could choose to remap Caps Lock to Ctrl, with the bottom left key then being Fn, and the key immediately to the right of the bottom left key being Caps Lock. For those who want the Caps Lock on the same keyboard row as A, the DEC keyboards like the VT100 keyboard, the LK201 and the LK401 were nice: the Caps Lock key was placed between the Ctrl key and the A key.
**I am aware this can often, but not always, be done in the O/S software or with other tweaks.
