What ⃢ means
It draws a screen-like frame around one preceding character.
A joint proposal from the United States and Unicode in 1997 described a 4:3 frame meant to resemble a screen and proposed it for keyboard notation. Unicode working-group minutes accepted it as a new character in 1998. A 2010 proposal for the ISO/IEC 9995-7 keyboard-symbol standard later used it in named sequences for scrolling and help.
Why does the frame float or disappear?
It needs one base character; font support controls the frame.
Place it immediately after one letter or symbol. An enclosing combining mark cannot stretch across several ordinary characters, so after a word it does not frame the whole word. Because the mark has no independent advance width, its position depends on the base character and font.
As of 2025, full support for enclosing marks was not widely available. One font or text engine may position the frame around the base character; another may detach the mark, drop it, or show a fallback box. Those are display differences, not a second meaning.
Technical and niche; in keyboard notation, it frames a preceding symbol to make a control sign.
Alone, this mark is not a complete screen sign; it needs a preceding character to enclose.

1Can it frame a whole word?
No. An enclosing mark applies to one base character; it does not extend across several ordinary letters.
