When it\u2019s ON, pressing F-keys runs the **standard** F1-F12 behavior; when OFF, they run the special icons. There\u2019s often a small LED on the **Esc** key showing which mode is active. ([download.lenovo.com](https://download.lenovo.com/manual/thinkpad_x1_carbon_gen13/user_guide/en/Use_the_keyboard_shortcuts.html?utm_source=openai))  \n- You can also change this behavior in the BIOS / UEFI under something like \u201cF1-F12 as primary function\u201d or \u201cHotkey Mode\u201d. ([gzhls.at](https://gzhls.at/blob/ldb/4/5/d/c/db083cc149bcc294dfe552467e169b1e1cdf.pdf?utm_source=openai))  \n\n---\n\nIf you tell me which **generation of ThinkPad Carbon** you have (e.g. X1 Carbon Gen 9, Gen 11, etc.), I can give you the exact functions on your model (sometimes they vary a bit)."
