Macros and shorcut keys

You can't use more letters than one, but you can combine a letter with Ctrl, Shift or function keys if you wish.

First, look at the following article even though it is dated:

Word for Word Perfect Users

Many WP users use macros to insert snippets of oft-used text. This is not a good use of this feature in Word. Instead, look at AutoText/Building Blocks and AutoCorrect.

Finally, it is possible to assign sequential keyboard combinations to macros (or, for that matter AutoText) but they are usually more trouble than they are worth. Such keyboard shortcuts consist of a single key combination (like Ctrl+1) to be followed by another key. For instance you could have Ctrl+1 followed by m for your mfp and Ctrl+1 followed by n for your nfp. You may want to focus on recording/writing your macros without worrying about assigning shortcuts until later. You can assign keyboard shortcuts to existing macros and AutoText through the customization dialog.

Keyboard shortcuts should be stored in the same template that holds the macros (or AutoText entries) they are calling. This is the normal template by default but that template is seldom where you want to keep them.
