That presentation is based on Gilles Castel's approach to snippet design. Mine has a fairly different philosophy with greater emphasis on visual representation. For example, my snippets for inverse limit and the empty set: snippet lim<- "inverse limit" iA \varprojlim endsnippet snippet o/ "Empty set" wA \emptyset endsnippet However, whichever you prefer, I highly recommend looking into the following two snippet classes of mine: snippet !! "inline math mode postfix" A \$$0\$ endsnippet snippet "(\S+)!!" "inline math mode postfix" Ar \$`!p snip.rv = match.group(1)`\$ endsnippet snippet "([A-Za-z]+)@@" "Autoformatting common functions" rA \\`!p snip.rv = match.group(1)`{$0} endsnippet Although they are very simple, I am extremely proud of them because they make math insertion so much easier: they turn math mode and calling macros into a postfix call, which is very natural for most of us. Try them and I promise they will help. To see how nice they are, to display $\log{\log{\log{x+1}}}$: !!log@@log@@log@@x+1
