A four-pane window mark identifying the Windows modifier key.
Also known as: Super key, Start key
A four-pane window outline marks the Windows key, which opens the Start menu alone and forms system shortcuts in combination. It is a vendor mark rather than an encoded character.
Pressed alone it opens the Start menu on Windows, and held with another key it forms a system-level shortcut.
Contexts: Software
On keyboards sold for Linux and on generic keyboards the same physical key is marked differently or left blank, and is referred to as the super key.
Contexts: Software
A square divided into four smaller panes by one vertical and one horizontal gap, the whole usually drawn tilted so the panes read as a window seen at an angle.
Both are used in software contexts.
