restricting movements to x,y,z for the handicapped I know that when you want to restrict movement or scaling to a certain axis you hold down the keyboard key corrresponding to the axis that you want isolate but I have a problem I am handicapped and only can only use 1 hand to move the mouse. 

Is there any other way to restrict which axis you want to operate on?

It would also help if when you select move or scale the direction arrows are displayed. It seems that the arrows become visable only occasionally. Is there any way to get them to show?
You don't have to hold down they key, just press it once. So you should be able to do it with one hand.

The arrows/gizmo appears if you select the move/rotate/scale tool from the toolshelf (top left). That should allow you to control your objects using just the mouse.



You used to be able to draw gestures to control movement too, but I think that has gone now. This add-on looks like it might help in your case, but I haven't tried it myself: Gesture Ops
