rewriting XMPfiles, keyword hieracystrings, templates

Hi, i am a new Bridge user.

usage for organising my source files, search tool and updating or creating XMP-sidecars. (first look is promising.)

Lot of things to read to understand the posibilities but as start up i am interested in some differences.

1) i understand i can make a "sjabloon" a auto fillin template.

how can i make it a automated writing and can i make it work for all images i did createalready a xmp for? (Do i need to selected and write all images by hand piece for piece for folder by folder?)

I made a sjabloon and  did a multi select images applied the sjabloon.

That worked and folder not so much.

brings up a other thing: i see sidecars like "dop files" in the folder thumbnails.

- can i create "asociated file links" so when i replace a rawfile the dopfile and the XMP-file go with the rawfile?

- can i hide the dop files?

2) keywords, an other main thing i choose Bridge for.

i have hieracical keywords like:

"Family" then "my family" (in dutch "Gezin" as in the household) and then the names which are in my household.

I was used to just click the name and the treepath was also selected but not shown. so i could search on "family" or houshold or a name to narrow down

The keyword section is a bit crowded if all entry's are visible.

How does Bridge work in this matter?

(if i click a household member the keyword household isn't checked and if  just use the name  and filter on "household" those arn't visible wile it's in the tree list as family=> householde=> name1, name 2, name  3, name 4 (so i would like to see all keyword tagged by those name1234 if i click family)

(now i have to click name1 then up the tree to "household" again up the tree to "family" and box them all before i have this function.)

I try to understand the limitations before i reorganise the xmp's.

thanks in advanged.

Edit: found the preference keyword thing for one click to the top. ( no three clicks any more) only they show all still)
