Hi,
if you use MachScreen do the following:
select the button "toggle mist coolant"
copy the selected button by clicking CTRL C
paste the button by clicking CTRL V
move the Cursor slowly until the shape changes to a crosshair
while the crosshair is shown hold down the left mouse button and drag the button to the place you want your flood coolant button and leave left mouse button
double click 113 in the property dialog and change it to 114
save the screen set and load the new screen set in Mach3.
If anything goes wrong, use the CTRL Z keys for undo the last Action(s)
