Suggested alternative key layouts for IPAC2?

[jimmy2x2x]

I've just wired up my first IPAC2 and love it!

Such a joy to work with, a great hassle free product, love it

Now Im looking to change the default keys

Having 2 issues so far

1) with Model2emulator - hold down ALT with some other keys causes pauses

2) with Steel Saviour - it is expecting 'enter' to navigate through the menus (cant redefine that key)

So Im thinking about getting rid of replacing CTRL with ENTER, and ALT with an unused key

I always thought it was odd to have CTRL and ALT used as default keys as they are used for operating system functions

Any thoughts?
