Shift+Spacebar+Moving Backward

Is this a bug? or just odd implementation? create a new template (used first person for this),

create a Left shift event that print a string.

create a Spacebar event that print another string.

simulate as if you were running (with shift), and then jump, the string of spacebar will print moving everywhere except backward. if you do the same with any other key instead of shift it will work…is shift cancelling spacebar function for some reason? in my main project shift event always triggers, as expected, but spacebar input seems to get consumed.

nobody can give me the heads up on this basic issue?

solved and closed

I’ve been watching this question and I could never figure it out myself. Could you share the answer please?
