define your shortcut normally with position etc.
the execution name is whatever you want and is used to refer to the execution where you would normally specify a !bang in the shortcut line.
and you can leave out any of the execution options you don't want to use

[code]
*Shortcut "anim" 0 0 ls_normal ls_hover ls_click #1t a:192 .none .none ls_exec

*layercut execution ls_exec
*layercut left !alert "left click" "exec test"
*layercut right !alert "right click" "exec test"
*layercut middle !alert "middle click" "exec test"
*layercut ~execution
[\code]
