Oh such good advice!
Aslo a little embarrassment on my part! Been spending a lot of time on TW5 lately to make my own use TW5 file for basis of a number life subject tiddlywikis. I must have skipped checking out the snippet icon. Sort of missed the good tree in the vast forest of icons and tools.
Also very interested in the AutoComplete tool.
So thanks for your fast replies and now changing my ToDo list for today to get into those two tools.
