Decreasing the size is difficult to do or to guess

[keryell]

I did not know that decreasing the size was working so I started to dive into the code to implement it but the code was actually there already to implement it... It happens that to have the "decrease" function working, an "increase" has do be done first with mod4+Alt+arrow and only then the Shift can be used to transform the "increase" in "decrease". Is it by design or just a side effect of the implementation? I would have expect mod4+Alt+ Shift + arrow working at the first place. I must admit that I choke on understanding the uncommented logic of start_loop() in init.lua and all the call-backs flying arround. :-)
