To clarify, I have a lot of code similar to:
dataframe1$third = dataframe1$SECOND - dataframe1$FIRST
I want all of the columns be small letters, such as:
dataframe1$third = dataframe1$second - dataframe1$first
Or else all CAPITALS.
Ctrl + Shift + U converts text to small letters, but I do not know how to get all CAPS.
I am reluctant to modify keyboard shortcuts.
I guess I will just use the convert to small letters option.
