Troubles with IPTC Metadata setting

[pie.photo]

I am a longtime TP7 user. Some time ago I bought TP9 but I am not able to do my workflow with this new version.
My problem in detail:
Some (basic) keywords come from Lightroom when exporting the developed RAW-file.
Then I start ThumbsPlus and scan the folder with my new images.
Next step - I select various images at the same time to give them a keyword (CTL-K). This ist very fast and still the same as with TP7.
But at the end I want to write all keywords from the database into the IPTC-keyword. With TP7 I started the IPTC-Editor, pressed CTRL-K and klicked on the OK-button - finished!
How can I do the same with TP9? I cannot find a way to do this.
How can I combine the keywords from database and the already existing IPTC-keywords in IPTC?
For me this is the only reason why I am still working with the good old TP7.
Please can you make me a happy TP9-user - Many thanks!

In TP9 you select the images and then use Image | Batch Edit Metadata.

In this case, to write the database keywords to IPTC keywords, you enter:

[*]FIELD: Keywords
[*]OPERATION: Set (or Append if you don't want to overwrite any existing IPTC keywords)
[*]FROM: Image Info > Keywords
[/list]

Then press Add, and the operation will be put on the operation list. The operation list (or 'batch') is what will be performed when you press OK. You can save this list for future re-use.

Thank you Daan
Now I understand better the usage of "Batch Edit Metadata".
I was too much focused to find something that combines IPTC- and DB-keywords.
Yes, this works fine. I only have to be sure that all embedded IPTC-Keywords are already read in to the database. Then I can use "Set". If I use "Append" a lot of keywords are written twice to IPTC.

Next step will be to set up a TP9 database on my NAS box.
