Feature request: Bind [home] key to 'zoom to page'

[hzeller]

The eeschema editor binds the home key to zoom out all the way to the main schematic, which is very familiar to users of KiCAD schema editor.

Since this zoom-out feature already exists in KiCanvas (but not bound to any key as far as I can tell), it would be beneficial to provide the same keybinding for users to feel right -- pardon the pun -- at home.
