You can switch the selection mode of KVideolist by either choosing "Multiselection->Toggle selection mode" or by clicking on the button called "Single selection" at the bottom of KVideolists main window. If You are in single selection mode (the default mode) You can choose only one of the movies. Itīs very useful when viewing Your movies. In multi selection mode, KVideolist enables You to mark all movies You select. Now the menu "Multiselection" allows several options which will be described here.
If You select this, a small window will open, where You can select what should be set on all selected movies. You can set single attributes like "Stereo" or the Subclass. If You leave an option to "Ignore", nothing will be done here. "Set attributes" is very useful if You have a large database, and want to categorize it into Subclasses.
Here You can delete all the movies You have selected.
Although this basically works, it is not ready for public use. If You are interessted in using this function, please wait for the next snapshot releases. Be prepared that KVideolist will crash when trying this.
