Question

1. what is the difference between a keyboard shortcut and a macro in microsoft word?

a keyboard shortcut is prebuilt by the developers of microsoft word and can never be changed, while a macro can be set by the user.
a keyboard shortcut connects a key combination to an action, while a macro is a custom set of actions that can be run from the macros menu, attached to a ribbon button, or connected to a keyboard shortcut.
a keyboard shortcut can only use alpha - numeric keys, while a macro can use any key on the keyboard.
word only supports macros, not keyboard shortcuts.

Explanation:

A keyboard shortcut connects a key combination to an action. A macro is a custom set of actions that can be run from the Macros menu, attached to a ribbon button, or connected to a keyboard shortcut. This clearly differentiates the two based on their nature and functionality.

Answer:

A keyboard shortcut connects a key combination to an action, while a macro is a custom set of actions that can be run from the Macros menu, attached to a ribbon button, or connected to a keyboard shortcut.
