RISC OS Mouse settings

I am left handed and I have always used a mouse with my left hand. When working in RISC OS I am always just out of habit clicking with the wrong finger. Other operating systems typically have a setting which swaps the left and right button. I have not found any setting in RISC OS that would make that swap.

Is there such a setting, or some utility that allows one to make such a setting?

thanks

Use KeyMapper: it’s supplied with the RISC OS Direct build, or can be downloaded from http://effarig.co.uk/riscos/

The necessary commands are:
*keymap 114 112
*keymap 112 114

Thank you very much Mr. Painting, you made my day.
