Since I couldn't put in the checkboxes, I settled for this which works fine; click to select, click to deselect: Next I will figure out how to make it say 'deselect' when the row is already highlighted.
[file=folder=link|private]
<tr class='{.if not|{.or|{.get|can delete.}|{.get|can access.}|{.get|can archive item.}.}|non.}selectable {.if|{.mod|{.count|row.}|2.}|even.}'><td>
{.if|{.get|is new.}|<span class='flag'> NEW </span>.}
{.if not|{.get|can access.}|<img src='/~img_lock'>.}
<a class='the-item' href="%item-url%"><img src="%item-icon%"> %item-name%</a><div style="float:right;"><input type="submit" value="{.!Select.}" style="font-weight:bold;" /></div>
{.if| {.?search.} |{:{.123 if 2|<div class='item-folder'>{.!item folder.} |{.breadcrumbs|{:<a href="%bread-url%">%bread-name%/</a>:}|from={.count substring|/|%folder%.}/breadcrumbs.}|</div>.}:} .}
{.123 if 2|<div class='comment'>|{.commentNL|%item-comment%.}|</div>.}
