Quick background: I use spreadsheets for action logs. From week to week, I
record what has changed from my last communication. I usually set the entire
cell to normal black unbolded. I add a line which has changed since last
communication and then set that new text to bold blue.

I want to find a way to use a hotkey to change my selected text to bold blue
without having to take my hands off the keyboard.

Is this possible?
