 * `:Disarm`: Remove a runtime file's maps, commands, and autocommands,
   effectively disabling it.
+* `:Execute`: Execute part of a Vim script.
 * `:Scriptnames`: Load `:scriptnames` into the quickfix list.
 * `:Verbose`: Capture the output of a `:verbose` invocation into the preview
   window.

+:{range}Execute         Execute the VimL given by {range}.  This works by
+                        writing the selection to a file and sourcing it.
+                        Script local variables won't work as you expect,
+                        so it's preferable to use |:Runtime| if you can.

+:Execute                Execute the top-most VimL structure at the cursor line
+                        (for example, a function definition, or augroup).
