I am talking about macOS. What's the key combination?

@sksundram the key combination is command + escape, you can find it on the fourth line hs.hotkey.bind({'command'}, 'escape', function ().

@truebit do you happen know how I could get this to come out of the right side rather than the top? I'm digging into Hammerspoon's docs but there's a lot to go through and it's all new to me, so a point in the right direction would be very appreciated.

After remembering that Spaces are Workspaces/Desktop this was much less confusing :-) I needed to be looking at setFrame.

In case anyone interested comes across this, I did this:

    local screen = win:screen();
    local max = screen:frame();

    winFrame.x = max.x + (max.w / 3 * 2)
    winFrame.y = max.y
    winFrame.w = max.w / 3
    winFrame.h = max.h

    print("winFrame="..tostring(winFrame))
    win:setFrame(winFrame, 0)
