Thanks Dennis!
I find the current implementation for SQL keywords works very well - there are radio buttons under SQL Server->Formatting in the Keyword case area that allow me to choose Uppercase along with a checkbox to Autocase keywords. However, I can see how that could become difficult to set up for multiple different syntax types.
I can see using the case to match how a symbol is defined in the list. IOW, I would add words to my function or library symbol list as I do now but make sure I entered them in the case I would prefer when typing them into code. This would be similar to aliases.
My suggestion would be to somehow include it with the coloring so that you could chose foreground color, background color, font style, and character case all in one place. After all, the editor has to determine the word element and its delimiters in order to color properly... it shouldn't be too difficult to change the case at the same time as changing the color. (that's just the appearance to an outsider - I really don't know how difficult it would be to code.) The difference is that if I decide sometime in the future that I want lowercase or proper case instead of uppercase then I would only have to change one setting. With the "type them capitalized as you want them" list, I would have to go back and retype every keyword to change their case.
Thanks again.
