Fluor is a macOS menu bar application that automatically switches the behavior of the keyboard's Fn keys (Apple function keys vs. standard F1-F12 keys) based on the currently active application. Users define per-application rules through a rules editor, and Fluor applies them on the fly.

Use cases

• switch fn keys to F1-F12 when using IDEs or terminals
• use Apple media keys in most apps but standard function keys in development tools
• automatically change keyboard fn key mode per application
• manage keyboard function key rules from the macOS status bar
• set a default fn key mode and override it for specific apps

When to choose

• you're on macOS with a keyboard that has dual-mode fn keys
• you want per-application fn key behavior without manual toggling
• you prefer a lightweight, open-source menu bar utility

When to avoid

• you're on Linux or Windows
• your keyboard has no fn key row or dedicated mode switch
• you need a maintained project — the README is out-of-date and development appears stalled
