As the title suggests, the key binding for content assist in my Spring Tools Suite has been Alt+/ by default since installation. However, one day after some unrelated settings, the content assist stopped working(i.e. not popping out that box). So I ventured into the preferences menu and only to find out that the key binding for content assist is still Alt+/. As I tried to rebind it, I pressed Right Alt+/on my keyboard, only to see the Binding column for content assist showing the combination Ctrl+Alt+/.
Also, by pressing Right Alt+/ when binding, the Binding column for content assist is actually showing the Ctrl+Alt+/ twice,(i.e. [Ctrl+Alt+/,Ctrl+Alt+/]).
When Right Alt is pressed during binding, the column would show Ctrl+Alt+, by pressing the / while holding Right Alt, the rest of /,Ctrl+Alt+/ pops out.
My left alt works as usual, Left Alt+/ would give me the regular Alt+/, and only once.
This is a bug only for STS, and is not showing on Windows and other programs.
I'm using version 3.9.7.RELEASE for STS
