RE: macros
a macro is a sequence of steps / commands that can be stored and then recalled with a single click or keyboard stroke.
For example, in Excel you may want to create a button that when pressed, will change the margins of a page, add gridlines, and change the Font to bold. By using a Macro you could record this action, and any time you press the button, it would repeat those steps to your active worksheet
I hope that makes sense
