Not to be confused with VST and VSTi.
A MuseScore plugin is a small piece of software that adds extra functionality to the program. A plugin need to be enabled first, and then executed by using the Plugins menu. Some plugins come pre-installed, they are disabled by default. There are also plugins created and shared by other musicians, anyone can download and use them.
Updating works the same way as installing, but remember to remove the files from the previous version to avoid duplicate plugins!
To assign a keyboard shortcut a plugin, use Home: Plugins or Plugins: Manage plugins....
