LyX ⇒ Can I change the space bar behaviour in LyX math mode?

[wiseowl]

When typing an equation in LyX math mode, pressing the space bar will sometimes exit the equation. This is annoying because I will often press it by accident. Sometimes I am typing fast and I immediately press backspace, which deletes my entire equation.

So my questions are:

• 1. Is there a way to disable this space bar behaviour in LyX 2.2.1?
  
  2. Is there a way for the backspace key to delete the last symbol/element in the equation instead of the entire equation?

I have looked in "Preferences" but didn't find any relevant options. Perhaps there is an under-the-hood solution...?

EDIT: it looks like someone has tried something similar:

No problem, thanks for understanding and for updating the link to here.
