-Contribute a menu item for a command to the editor or Explorer. The menu item definition contains the command that should be invoked when selected and the condition under which the item should show. The latter is defined with the `when` clause which uses the key bindings [when clause contexts](/docs/getstarted/keybindings.md#when-clause-contexts). In addition to the mandatory `command` property, an alternative command can be defined using the `alt`-property. It will be shown and invoked when pressing `kbstyle(Alt)` while hovering over a menu item. Last, a `group`-property defines sorting and grouping of menu items. The `navigation` group is special as it will always be sorted to the top/beginning of a menu.
