LMB click on an item in Konqueror's window and it will be "activated". Thus
LMB click on an icon in the Toolbar to do whatever that icon is supposed to do.
LMB click on an item in the Menubar to make that menu drop down.
LMB click on a menu item to do that thing.
LMB click on a link in a web page will make Konqueror follow that link.
LMB click on a directory icon or name and Konqueror will descend into (show the contents of) that directory
LMB click on a file name or icon and Konqueror will do whatever it thinks appropriate, based on the file type. In general this means opening HTML pages, or previewing text, image or Koffice files, embedding then within Konqueror's window. ("Preview" means that you can see the file but not change it).
Konqueror decides what the file type is by matching the filename extension against against a list of known types. If that fails it tries to guess the type from the file contents. You can change the list of known file types and associated actions and add new types, see the section File Types and Associations.
MMB on a file or directory name or icon does essentially the same as LMB except that it does it in a new Konqueror window.
