Does this keyboard have an auto-chord or one-finger-play chord function? (In other words it will play a C chord, just by pushing a C key.

No. It has an "arpeggiator" feature that created rhythms with whatever chord you play, but you have to know chords. This is not a child's keyboard, this is a tool for musicians who are doing composition or arranging. It does have very good sounds, plus it has a touch sensitive keyboard and MIDI connectivity. It does exactly what I hoped it would do for me: it gives me quick, easy MIDI input into my computer; it gives me enough polyphony to input big, rich chord voicings; and takes up next to no space on my desk.

Is there a case made for this or a case/bag that would work?

There is no dedicated case for this. If it helps, you might be able to find a small keyboard case, this product is about 20" x 2 1/8" x 8"
