My Slate (window manager) configuration for quickly toggling browser width, handy for responsive web design workflows

slate.js

// Slate is here: https://github.com/jigish/slate/
// Widths for frontend development
var pushToScreenWidth = slate.operation("move", {
  "x": "screenOriginX",
  "y": "screenOriginY",
  "width": "screenSizeX",
  "height": "screenSizeY"
});

// dup duplicates the operation and changes the given parameters
slate.bind("1:ctrl,alt", pushToScreenWidth.dup({
  "width": 400
}));
slate.bind("2:ctrl,alt", pushToScreenWidth.dup({
  "width": 600
}));
slate.bind("3:ctrl,alt", pushToScreenWidth.dup({
  "width": 800
}));
slate.bind("4:ctrl,alt", pushToScreenWidth.dup({
  "width": 1000
}));
slate.bind("5:ctrl,alt", pushToScreenWidth);
