Shift+F10 works on Windows and Linux GTK (not Qt) apps, but it's not self-documenting unlike the menu key. Also bring back keyboards with external media keys that don't require holding Fn to either change volume and tracks, or press F# key shortcuts. Also please give me an EC firmware which maps top-row keys to media keys when pressed alone (for convenience), and to F# keys when either Fn or any other modifier keys are held (so you don't need to add an extra key to complex modifier chords relative to on desktops).
