Here are some macros that I find very useful and that may be useful for others as well. The most useful macro for me is the comment/uncomment macro. Assign this macro to a key (ctrl-/) and then use it to toggle comments on a single line of code or a block of code. For single lines, the indention level remains, for blocks of code, the comment is placed at the beginning of the line. I think this comment macro is a little more powerful than the existing one on the site. Hope some people find them useful.
