Not sure if it's worth the bother. Would be a good excuse to learn regexs though.
There are ways around it through. Like Sublime has string replace so you write your stuff using some HTML, ie <b></b>, for highlights you can replace all instances of '<' with '[' to convert it over to bbcode.
This makes it possible to actually skip coding too. As I've mentioned else where you can write a class table using next to nothing. Like
{20; +15; +6; +6; +12; special}, then just replace '{' with table2's row and cell tag, '}' with the ending ones, and all instances of '; ' with an ending cell tag and a new starting one.
And in the case of Notepad++, you hit the record macro button and do all of the replacements at once just like you normally would (no filling in special boxes or anything) then map it to a single keystroke for the next time.
