Some languages (like SQL) have a long standing tradition of using upper case for the keywords. But to me, it’s kind of hard to type in upper case, but at the same time I like the way it looks when a stored procedure is nicely cap’d. This video shows you how to select a word, and make it all Uppercase, or all Lowercase. It can also be done from the Edit menu.
[CTRL]+[SHIFT]+U = Make Uppercase
[CTRL]+U = Make Lowercase (this is weird to me, they seem backwards)
