MMF - Mac Move Focus

MMF is a small macOS utility that lets you switch focus between monitors using only the keyboard.

Why I Built This

Working with multiple monitors, I constantly switch between tasks: writing code on one screen, checking docs or videos on another. As vim user I got tired of interrupting my rhythm just to move the mouse across displays.

What It Does

• Detects all active displays
• Determines which display your mouse is currently on
• Moves the cursor to the center of the next monitor
• Identifies the topmost valid window on that display
• Brings that window to focus using Accessibility APIs

Requirements

This tool is meant to be used with skhd, a lightweight hotkey daemon that allows you to bind MMF to whatever keyboard shortcut you prefer.

Installation

Clone the repository:

git clone https://github.com/gabrielerandazzo/MMF.git mmf
cd mmf

Make the setup script executable and run it:

chmod +x setup.sh
./setup.sh

This will compile the tool and place the mmf binary in:

~/.config/mmf/mmf

Usage with skhd

Edit your skhd configuration file:

~/.config/skhd/skhdrc

Add a shortcut of your choice Eg.:

ctrl - m: ~/.config/mmf/mmf

Reload skhd:

skhd -restart
