Issue first raised two years ago in "Control-Y does not do anything" seems to still be in play (i.e. doesn't work). Is this a bug or deliberate omission in the lightweight implementation of VIM key bindings? Thx
The response in previous thread claimed VIM has no such Ctrl-Y binding. That is incorrect. See below from help entry.
In VIM (launched from a Terminal on MacOS) I execute following.
It opens help entry labeled "CTRL-Y" in the Scrolling section and reads as follows:
"Scroll window [count] lines upwards in the buffer.
The text moves downwards on the screen.
Note: When using the MS-Windows key bindings CTRL-Y is
remapped to redo."
