This is a simple workflow I set up to resize windows.
The keywords are as follows:
t = top
b = bottom
l = left
r = right
tl = top left
tr = top right
bl = bottom left
br = bottom right
c = centered
f = full
I used to program these as hotkeys in Alfred 1 but I find that a few extra keystrokes is worth not having to remember 10 different hotkey combinations. The Alfred 1 project I based this on can be found here: http://projects.jga.me/layouts/#toc3
