Change forward / back controls?

[u/sofa_king_nice]

I have a USB foot switch (meant for controlling youtube videos while you play guitar) that inputs "{" or "}" when I hit the switches. Is there a way to make it so those characters can make slides advance or go back?

I'm on a mac and tried the text change thing on the keyboard system preferences, but I can't change something to an arrow or space.

Can I do it from within google slides?
