I'm sorry, but I do not know much English, so wrongly asked.
how to assign the desired key, I know.
The problem is that I want to leave everything standart view settings: pictures, texts, etc. as it is, and only on the zip-archive to check what their view.
and that I want to set up in "File Type Setup" tab Viewers (key "F3"!!!)
how to assign the execution of my script for *.zip?
there can only be: "Program Path / Internal Extension (" MC Picture Viewer "and" MultiDataViewer ") / Windows Action"
can somehow use MC.RunUserCmd?
Ideally - to do the treatment by the Commander of double, triple, etc. extensions.
I can write view.cmd and use it to determine the file type and assign the desired program. But then it is no need to configure the file types in the Multi Commander and is the main charm of Multi Commander - own scripting language.
