What does this mean in xmodmap?

I am really hoping that someone will take pity on me.

I copy and pasted this command from the internet and then realised I didn’t know how to reverse/reset it.

The idea was to change the behaviour of my mouse temporarily.
This is the command I used:
xmodmap -e "pointer = 4 5 3 1 2
Sorry not in code tags as I am unable to highlight with mouse.
Thank you very much.

xmodmap -e pointer = default

should set it back

Note I don’t think the changes made by xmodmap are persistent so a reboot should reset things also

Thank you so much. I can’t believe I did something so silly. In fact

xmodmap -e "pointer = default"

worked.

At least when I try ‘speed baking’ again, I shall resist the urge to mess with the mouse.
