search-replace table (made by S.P and D.P)

Shawn Pringle has created a table (more comprehensive than this version) to summarize the available search-replace routines in Euphoria. Derek Parnell then made an html variant. I have merely converted Derek's table into creole format so see how it will fit into to documentation.
This table looks like it should be added as a "miniguide" in the documentation. I am willing to turn this into an article. If anyone has some ideas, just give me a few hints or rough text, and I will finsh the work.

Notes:
- the wildcard syntax is much "friendlier" than "regex" syntax (but much less powerful)
- built-in routines shown with no namespace prefix
- routines from libraries are using a prefix
- include std/search.e as search
- include std/regex.e as re
- include std/wildcard.e as wildcard

Some questions:
- would "element" be a better term than "memember" in this table? ( as in, we think in terms of elements of a sequence)
- can I assume that the speed advantage goes as: built-in (fastest), std/library, regular expression (slowest)
