Apps :: how can I configure left hand mouse?

I want to configure the mouse to left hand, I dont find any app to do so.

bata, I assume you mean swap the left and right mouse buttons? Enter this line in a Xterm window:

xmodmap -e "pointer = 3 2 1 4 5"

If that doesn't work you can reset it back to the default by typing:

xmodmap -e "pointer = default"

Cliquer, it say
xmodmap: unknown command on line commandline:0

thanks I have been looking for a way to make my mouse left handed in DSL 2.1
