This example shows a configuration file for Slate, a macOS window manager, that defines keyboard shortcuts to position and resize windows across the screen. It uses aliases with arithmetic expressions (e.g., `screenSizeX/2`) and named bindings to apply abstract positions like halves, quarters, and centered regions. The file also binds specific commands to focus applications, such as Google Chrome, and uses key combinations with modifiers like `cmd`, `alt`, `ctrl`, and `shift` to trigger window actions and monitor switching. The code is plain text with a simple syntax of aliases and bindings, not a visual library or data API.
