Stay on Top
From TED Notepad
Stay on Top (Alt+O+T)
If checked, TED Notepad stays in front of other common applications even if not active.
Note: If more than one application is in a stay-on-top mode, their order on the screen depends on the System. There is no way to ensure, that any particular one will be the topmost one of them.
Note: The reason the hotkey is a combination of menu mnemonics, instead of using a more usual hotkey combination, is to avoid accidental unwanted activation of stay-on-top mode by new less experienced users.
