slime-selector command is for quickly switching to
important buffers: the REPL, SLDB, the Lisp source you were just
hacking, etc. Once invoked the command prompts for a single letter to
specify which buffer it should display. Here are some of the options:
slime-selectors's available buffers.
*slime-scratch*buffer (see slime-scratch).
slime-selector doesn't have a key binding by default but we
suggest that you assign it a global one. You can bind it to C-c s
(global-set-key "\C-cs" 'slime-selector)
And then you can switch to the REPL from anywhere with C-c s r.
def-slime-selector-method can be used to define new
slime-selector to find.
