Here is a macro set that sets the brush size to 10 when you type "1", 25 when you type "2" and 50 when you type "3", and it sets the color to black when you type "4" and to white when you type "5". It works with the built in brush tool that is installed by selecting "Brush" from the toolbars's ">>" menu. It requires the latest ImageJ daily build (1.49b2).
macro "Small [1]" {call("ij.plugin.tool.BrushTool.setBrushWidth",10);}
macro "Medium [2]" {call("ij.plugin.tool.BrushTool.setBrushWidth",25);}
macro "Large [3]" {call("ij.plugin.tool.BrushTool.setBrushWidth",50);}
macro "Black [4]" {setForegroundColor(0,0,0);}
macro "White [5]" {setForegroundColor(255,255,255);}
