Mac convert tip #2: install a window manager
Hitting the Windows key together with one of the arrow keys provided a fast way to resize a window to fit the left or right half of the screen in the Microsoft world. For mouse users, dragging the window to the edge of the screen achieves the same result. This is really useful if you’re writing in one application while referring to research in another. I was pretty disappointed to find that OSX didn’t provide an equivalent capability. After a day or two of manhandling windows into position, I went looking for a better solution.
All of these applications will let you replicate the behaviour of Windows. They offer more control than Windows by offering configurable keyboard shortcuts and snap areas along with other advanced options. If you’re not currently running a window manager, they are worth checking out — especially if you have a large display.
