Thx for the explanation
I will try it :)
PS You have not written what we must write for the Angle in column of the Shortcut

Pss an you must write for the first for example
Alt+X QuickSplit_XYZ X
Alt+Y QuickSplit_XYZ Y
Alt+Z QuickSplit_XYZ Y

becauce I have written QuickSplit_XYZ X (y or Z) and nothing work !!! :)
