Answer 1

Textwrangler uses ordinary regular expressions when the "Grep" option is selected in the search dialog, so any basic tutorial on regular expressions will tell you what you need to know.

As it stands, your question is a bit unclear. What do you mean by "any two numbers"? If you want something that will match wordx[y], where x is any single digit and y is any pair of digits, then this pattern will work:

word\d\[\d\d\]

By way of explanation, \d is a pattern that matches any single digit (0–9). You also need to escape the [ and ] characters with backslashes because these characters have special significance in regular expressions when unescaped.
