Select object by user defined properties

i need a script like this for redshift and shaderswitch usage

Hey crystal3d, I found the solution:

-- for k in selection as array do

(

 name_ = "mybox"--(getuserprop k "name")

 select (for o in Objects where o.name != undefined /* and (not o.ishidden) */ and (getuserprop o "name") == name_ collect o)

)
