Is there a way to disable the command line window?

Question

Often the mechanism to end up in the command line window is a transposition typo q: instead of :q when I intend to be closing Vim.

You can imagine the frustration at this point because the program state is now such that I have to (more carefully) type TWO more proper :q to achieve my goal. Although I do have, and can use a nice easy normal mode chord bind <s-q> for :q, my muscle memory and habits (using non-augmented vims) lead me to continue to use :q, so it is not a full solution.

In an effort to mitigate this situation, I have

nnoremap q: <Nop>

This works, however, now the q has an input delay (due to being bound now) and therefore causes the action of exiting from recording a macro/recording to be latent.

How can I remove my ability to enter the command line window without introducing such consequences?

Answer 1

I have not found a way to disable the command-line window, but, I have eliminated the need for the q: bind of mine, by removing it and changing the rest of my vim config to allow my command-line window to work again as intended.

You could say this is solved by application of the XY problem principle.
