I love this kind of efficient working, but I personally have found eliminating the mouse as much as possible is the best way and that's worked for me for some time. I was initially intrigued by this as it may be useful to have a quick way to send something to (a folder on) the desktop for example, however I still would find using a combination of ctrl+c then ctrl+v (maybe adding a windows+D in-between there to get to the desktop or windows+e to bring up 'computer' followed by either usage of alt+tab to switch between windows, or tab to move around in a window and the arrow keys or even F3 in some cases if the destination folder is buried obscurely in a potentially unknown location or is simply too many folders deep amongst highly populated folder structures)
Now is there anything anyone can build on or pick apart with my system. I'm very open to criticism as I have after all criticised this method of using the mouse. Perhaps there's something I'm missing or some kind of flaw with my system for some?
