SQL Text to Numeric
this basically strips the single quotes out of the selected portion of an SQL statement.Let's say that you've built an SQL statement using a where clause which has a string variable in it, and you realize it was a numeric, rather than a string variable. Either highlight that portion, or the entire SQL statement and run that command - it strips the single quotes and voilá - you have a corrected SQL statement.

Response.Write Replace Double Quotes
This is another really powerful part of ASP Express. This is for converting a portion of HTML into a 'response.write' format. Naturally, if you have HTML tags, you most likely have double quotes around the attributes. Look at this bit of HTML:
<font Size="4" Color="#FF33CC">This is text</font>
by highlighting from the start of the first font tag to the end of the last font tag, you will convert it to:
Response.write "<font Size=""4"" Color=""#FF33CC"">This is text</font>"
The best part of this, is that it will work on large sections/multiple lines of HTML.
