The patch below adds a command `slime-inspector-previous-inspectable-object' and binds it to S-TAB in slime-inspector-mode. Moreover, the command `slime-inspector-next-inspectable-object' now accepts a prefix argument. The patch also makes wrapping around more reliable. I have adapted the code from the Emacs function `widget-move', which is used for similar functionality in Emacs Customize buffers.
