regarding the mouse and keyboard use in visual programming, i have used labview extensively. with labview, one normally assumes one hand on the mouse and another on the left side of the keyboard, which is used in a chorded manner in that it provides modifications to what the mouse is doing. this is common i think to other visual environments such CAD programs. then the hands join back on the keyboard for searching and quick drop. i think a hybrid setup like this can be powerful. it is under researched though. i am learning emacs at the moment, which is in the pure keyboard camp. while seemingly powerful, it does feel like a blast into the past and not so efficient in terms of learning curve or reasoning. so all keyboard and all mouse are a miss. i personally think a mix of keyboard, mouse, and touch is something to be explored.
