Are there other built-in functions for performing "table manipulations" to matrices? Meaning I would like to sort a matrix in ascending order based on a certain row's value, is this possible with a built-in function.

For example I have many pairs consisting of (value, description) and I want to organize them based on value.

Hopefully this is somewhat clear. I realize I could create a function to do this for me, but I thought maybe there was a built-in function.

Side question - Is it just me or does it seam like chrome, bing, etc. do a bad job of searching/indexing this forum?

Thanks!

csort is a universal algorithm [divide/conquer], built-in Smath.
Lot more matrix manipulation can be performed in Smath from user modules...
... lookup, truth table, rotation, nest/unest, list ...
