There is no option for it anywhere. To overcome it in a literal way, you'd need a one line macro that maps the key to being a space. It would look something like:
Application.OnKey "+{SPACE}", "{SPACE}"
but I do not write macros so it could need tweaking. Copied and modified from:
https://docs.microsoft.com/en-us/office/vba/api/excel.application.onkey
POINT TO REMEMBER: once run, it doesn't just end so you'd need a second macro to end it by remapping the Shift-Space ("+{SPACE}"
) back to being Shift-Space after you are done.
A non-literal way ("living with it with less suckage" or "workaround") would be to hit the CapsLock key before creating such formulas. Then the space will just be a space. Only an issue in case of needing to type non-cap text, then its "which sucks more?" Or in having to remember to do it each time.
(Each approach has something you have to do then undo when done, never forgetting.)
B:B + 2*C:C
thenD1 = B1 + 2*C1
,D2 = B2 + 2*C2
and similar for the remaining cells of column D. The same will happen for rows. It's also used to populate a formula to the whole table
