I didn't find the answer, so must post there.
I use vi (nvi-2.1.3) which is in a base and I found confusion.
If I print colon ( : ) and then press Esc then some window (buffer) opens in a bottom of vi editor.
There is no such thing in vi 1.79, but is only in nvi2.
.
I later realized that whis window is a history of ex commands typed earlier.
But I don't want use this feature because I can type colon by mistake and than I want to exit back to command mode with Esc similarly I do when exit from insert mode.
And I don't want to use ex history.
How I can remap or disable this feature?
