A quick way to see what commands are directly available with the use of the Ctrl+ is to simply go along the top menu and get each drop-down to activate. Look for commands that you want to access directly and make note of them. Even if you already have access to them with the Alt+, note the command. What you'll see is that there are probably quite a few that can be reached with the Ctrl+ and if you do that, you'll free up the corresponding alt key for your use.
I ran out of Alt+ keys years ago, but when DataCAD offered the Ctrl+, it made many new things go perfectly well with a single activation. My Move-Drag, both without a copy and with a copy became accessible with these two commands in my dcadwin.mcr.
R^;^F1^F1^
// Drag without copy
Y^;^F2^F7^
// Drag and copy
I think of the R as
Relocate and the Y as Cop
Y.
I'd guess that I switched a minimum of ten Alt+ key commands and either gave them new destinations like Drag (without copy) or Drag (with copy). Ctrl+ enhanced my customization tremendously.
Good luck,
