Toolbar headings rewrite

I am developing some software but the menu needs the headings rewriting to be different to what they are now. Example View Messages – maybe change to view mail Last AMS Message – maybe change to Last Message Send Message - – maybe change to Send Mail. These are all in the left toolbar They must look different.
