| "I really can not cope with all this script stuff I need just the simple access to --well-- Keystroke "actions" that I can get in most other programmes." 
Brian, you don't have to be able to write scripts to set up keystrokes, but because MoI is so open-ended it doesn't have many keystrokes set up as standard. Although this means that you may have to do some setup work, you can make the keystroke actions anything that you like, which should make them much easier to remember.
 
Say you want your SaveAs keystroke to be the key 'a'. This is how to do it.
 
1) Click on the Options button in MoI.  
2) Click on 'Shortcut keys'.  
3) Click the 'Add' button. That will insert an empty row in the dialog box. 
4) Enter the letter 'a' (without quote marks) in the Key field on the left of the empty row. 
5) In the Command field on right enter 'SaveAs' (again without the quotes). 
6) Hit the Close button and the dialog will save your changes and disappear.
   
Now if you hit the 'a' button you should get the Save as... dialog pop up. 
In this way you can make MoI's keyboard shortcuts resemble whichever software you are most comfortable with.
 
As far as I can tell, the list of MoI's "native" commands is as follows (see below) so if you want to attach ArrayCircular to a particular keystroke combination, all you have to do is enter ArrayCircular in the dialog box as described above. For more complex commands you may need to use a script (just copy and paste one written by Michael) but for the sort of thing you mention standard commands should be fine and as you can see they are easy to add.
