>>> No the files that you indicate commands directory Why?

Hi Juan,

Just see my post above : http://moi3d.com/forum/index.php?webtag=MOI&msg=1139.5

If your shortcut "ALT+K" is for the "ConstructionLine" command, then you must install the script in your "Commands" folder. It is not a script that automatically installs with MoI.
That script works fine here...
