How to add tag A to all tiddlers with tag B

[Harry]

Hi all,

I have a question about adding tags. I have finished creating 800+ tiddlers and now need to add additional tags to some of them. What I want to do is that for all tiddlers that already have been tagged "NV-senator", I want to also tag them with "NV-legislator". Is there a way that I can do that in a batch? I found some posts on creating a button, but am really confused as a newcomer.

After that, I also want to attach tag "NV-legislator" to all tiddlers with tag  "NV-rep" . The complication is that some tiddlers may have already been tagged with both  "NV-senator" and  "NV-rep" , and therefore would have already been tagged with  "NV-legislator" . If I replicate the same process with what I did for the "NV-rep" tags, would it be a problem that the command may try to add "NV-legislator" tag to some tiddlers that already have it?

Really appreciate all the help!

I also want to attach tag "NV-legislator" to all tiddlers with tag  "NV-rep".

Try this:

<$button> add tags

   <$list filter="[tag[NV-senator]] [tag[NV-rep]]">

      <$action-listops $tags="NV-legislator" />

   </$list>

</$button>

Notes:

* The $button label is "add tags".  The button actions (the $list and $action-listops) are only performed when the button is clicked.

* The $list filter finds all tiddlers tagged with either NV-senator OR NV-rep.  Note that duplicates are automatically removed from the filter results.

* For each tiddler found, $action-listops adds the NV-legislator tag to the existing tags

* The tags list of any given tiddler are always unique, so even if you press the button again, it will not add a duplicate tag

enjoy,
