Playing around with a bit, the "expand" key under "[styling]" group controls the style of TCL {expand}-style keywords. I have no clue what this does in TCL, but it has to be {inside braces like this}.
As for the "wordexpand" style, I've no clue. I tried reading the lexer code but it makes no sense how it's organized WRT keyword sets, and upstream provides 0 documentation on lexers (except the C++ code itself).
Sorry I couldn't help more.
Cheers, Matthew Brush
Hi Matthew Actually, that helps a lot. Now I know that my plan will not work with the expand keyword (which has something to do with variable number of input arguments to a function). I'll use one of the other keywords, since I only need the tcl keywords. Thanks Arpit
