Mohammad, My Previous contribution to the scripts is in fact a demo of the first of a set of possible batch manipulation examples.
Here are a few more that illustrate the examples you are looking for, it is simply a matter of changing the selection filter and the action widget. Som action widgets have the $filter parameter, others do not and you need a list. <$list filter="[has[dummy]]"></$list> <$button> <$action-deletetiddler $filter="[tag[dummy]]"/> Delete Tiddlers tagged </$button> <$list filter="[has[dummy]]"></$list> <$button> <$list filter="[has[dummy]]"> <$action-deletefield $field="dummy"/> </$list> Delete Field in tiddler </$button> <$button> <$action-deletetiddler $filter="[has[dummy]]"/> Delete Tiddlers with field </$button> Whilst this shows the code if we were to package it for new users, not people learning tiddlywiki, we would always ensure we list what the button will effect. Make a macro and enable the filter to be passed (not hard coded). It would be quite easy to make a large set of these and make them available for almost every conceivable batch action, however if we are to go down this path we should decide exactly what we will provide so we can do it consistently and not face rework later.
