You can swap the mouse buttons, that is reverse the normal actions of the left and right buttons, as follows:
SYS "SwapMouseButton", 1
To restore the conventional functions for the buttons use:
SYS "SwapMouseButton", 0
Note that the mouse is a shared resource, so any change you make will affect all applications and utilities, not just your program.
You can discover whether the mouse buttons have been swapped as follows:
SM_SWAPBUTTON = 23 SYS "GetSystemMetrics", SM_SWAPBUTTON TO yes%
This will set yes% to zero if the mouse buttons are not swapped, and non-zero if they are swapped.
