Fn and Ctrl Key swap
Provided by the ASK Keyboard Dictionary
The Fn and Ctrl Key swap function is an option available on some Lenovo laptops including ThinkPads that allows the user to swap the position of the Fn and left Ctrl keys in software. For most of their history, ThinkPads had their Fn key placed in the bottom-leftmost position, a placement unusual in the laptop industry except for notably Apple MacBooks. Depending on the exact ThinkPad and whether the option is available, this option may be available in the ThinkPad's BIOS/UEFI firmware, in Lenovo Keyboard Manager, or in Lenovo Vantage.
