Well ive been playing around deeply with snippets in HS+ (and the macro manager), and so far loving it. Ive got the complete list of variables for HS sorted now and they are damn handy for working with. As mentioned i have already blogged some FuseDoc snippets that i created a week or so ago. Anyway for anyone interested heres the list of HS+5.5 snippet Variables:

• $${DATE}
• $${MONTH}
• $${TIME}
• $${DATETIME}
• $${DAYOFWEEK}
• $${CURRENTFILE} - Current file name (just the file)
