how to change winkey + (left/right) keyboard-shortcut behavior

Question

When you use the shortcut: winkey+left / winkey + right, the current window is attached to the side of your screen by 50% width. i would like to change this behavior, and attach it by 33.3% width

visual explanation:

Answer 1

The snap size is fixed for Windows 7 and Windows 8.

If you are looking for a custom size you might have to look for a third party program.

Answer 2

I am pretty sure you can't edit the size, but you could have a play with something from Microsoft

I personally have not used this program since I haven't had the need, but it might do what you want and it's from a 'trusted' source...

Answer 3

After some digging, i found a good solution. This is an open source called GridMove

the shortcut i'm using is winkey+numpad number instead of winkey+left/right arrow

if it helps, this is my 3-monitor .grid file (should be located in C:\Program Files (x86)\GridMove\Grids\jossef.grid

winkey+1 => left bottom

winkey+2 => center bottom

winkey+3 => right bottom

winkey+4 => left full

winkey+5 => center full

winkey+6 => right full

winkey+7 => left top

winkey+8 => center top

winkey+9 => right top
