tmw you want to bold several 5-letter words but don't want to have to add the } at the end so you make a command like \newcommand{\bbb}[5]{\textbf{#1#2#3#4#5}} and then just copy \bbb everywhere you want
(for those fortunate enough to have never seen Latex, that's a command that takes five parameters, but you can use it like \bbb words if you're too lazy to do \textbf{words})
