I have run into all kinds of traps while writing documents lately, and I keep failing to update every part of a template. I started thinking how convenient it would be to automate those updates. At that moment, I, who considered myself fairly proficient with Word, realized how little I knew. I planned to first learn about fields and templates, then VBA programming. Automating problem-solving is how we improve efficiency and accuracy.
Using fields:
In Word, press Ctrl+F9 to insert a field
Press F9 to update a field (select all and press F9 to update all fields)
Shift+F9 switches between field code and field result (Alt+F9 switches all fields)
Ctrl+F11 locks a field so it will not change during a global update. Ctrl+Shift+F11 unlocks it.
Ctrl+Shift+F9 converts all fields to displayed text.
