So I fractured my toe in a couple places during Soccer. Right now I'm in quite a bit of pain, so just trying to take it easy and heal for the time being. The Doctor says I'll probably be out for about 6 weeks.
I really want to try and keep in shape during that time. I won't be doing anything rigorous for a while, but any small thing I can do daily without needing my feet can help.
Leg lifts work pretty well for me. There are ones you can do for abs, hips, adductors, abductors, hamstrings, and basically anythingdown there. Standing or laying down works, it just depends how you can position yourself to avoid injuring your toes. I suggest getting some adjustable ankle weights and goto town with them. Also you can try plank exercises, but that might be too much foot action depending on the position...
Arm cycle is the first thing that comes to mind. A rowing machine or cross trainer may work (especially if you can pad around the area) depending on the severity of the injury.

It works up a sweat and makes me breathe harder than normal. I can't think of anything else to call it unless you want to generalize it as "exercise"...
Go with non-traditional cardio. Try some circuit training or high rep resistance exercises. Bench, shoulder press, rows, pullups, etc. If you can safely handle leg ext. and leg curls that would be great as well. Rowing machine may be an option as well. And maybe a cycle if at low intensity if it doesn't hurt your toe.
