Adding a class="  " to a column in a table

In preparing a table I wanted to highlight the entries in the first column. The page was Ctrl.html">Control of StrongED from Keyboard - it had several different tables.

All table entries were of this type

<tr><td>Home</td> <td>Start of text</td></tr>
<tr><td>End</td> <td>End of text</td></tr>
<tr><td>Up</td> <td>Caret up</td></tr>
<tr><td>Down</td> <td>Caret down</td></tr>

Search	"<tr><td>"@1*@2"</td>"
Replace	"<tr><td><span class=\"mt\">"@12"</span></td>"

In a instant, 141 entries were changed!

The Search expression

"<tr><td>"@1*@2"</td>" contains a start string then a marker @1. Markers do not affect the search string - they are simply there to tell the replace string what to do.
* means search forward in the text for the next item - which is another string.

The replace expression

"<tr><td><span class=\"mt\">"@12"</span></td>" I started off by simply copying the search string, replacing @1*@2 by @12, the adding the bits I needed to add, in the correct places.
