##### LaTeX to XML Math Delimiters - 35 entries

Vim is amazing when used to edit MediaWiki text, but typing "<math> . . . </math>" can be tiresome and frustrating if formulas are used often. LaTeX delimiters are so concise and even come in two flavors: "\( . . . \)" for inline math and "\[ . . . \]" for centered formulas. The goal is to perform the following conversions: "\( . . . \)" becomes "<math>. . .</math>" "\[ . . . \]" becomes "<center><math>. . .</math></center>"

##### Word frequency alignment - 198 entries

You've got to align the second column, but the spacing is inconvenient and there are nasty tabs in the way. If you're a "real Vim ninja," this could be very quick indeed...
