How to measure part in solidworks

One most important tool in solidworks is Measure (Tools>Measure..), it can measure for you in realtime point to point, point to edge and point face vice versa. The conventional length or radius can be view by clicking on the selected edge but this function has it own limitation. So Measure tool is very useful and frequently use. So why not put it in Keyboard shortcut. Right click on Command Bar, select customize, select keyboard, search for measure and put M as shortcut.
