"Autohotkey"
Free program from the early days of the internet.
Infinitely customizable to input phrases or even whole paragraphs off of 3-4 letter shortcuts.
for example: I type the letters r t o and it instantly converts to return to office
Also, all kinds of key combinations can send chart to nurse, etc: for example: you can write a script which will allow you to hit Ctrl M to send chart to Nursing (you don't want to do Ctrl N because that is new note!)
