As the title implies, the AM interface would be much friendlier if it featured keyboard shortcuts, not unlike those in Logic.
The most useful application for these would be all the saving/loading/copying operations of the preset window. Would be a huge time-saver and pain reliever if it could all be done without a single click. Having to point on that tiny preset number repeatedly can easily become torture when you rely as heavily on presets as I do (sorry if I'm constantly bringing this up, but AM has so much potential on this front!)
Also, it would be neat to be able to shift the highlight between contraptions on the properties window using the keyboard arrows (and from there do all the preset-related operations).
