+=head1 NAME
+
+ido_switcher.pl
+
+=head1 DESCRIPTION 
+
+Search and select windows similar to ido-mode for emacs
+
+=head1 INSTALLATION
+
+This script requires that you have first installed and loaded F<uberprompt.pl>
+
+Uberprompt can be downloaded from:
+
+L<https://github.com/shabble/irssi-scripts/raw/master/prompt_info/uberprompt.pl>
+
+and follow the instructions at the top of that file or its README for installation.
+
+If uberprompt.pl is available, but not loaded, this script will make one
+attempt to load it before giving up.  This eliminates the need to precisely
+arrange the startup order of your scripts.
+
+=head2 SETUP
+
+C</bind ^G /ido_switch_start [options]>
+
+Where C<^G> is a key of your choice.
+
+=head2 USAGE
+
+C<C-g> (or whatever you've set the above bind to), enters IDO window switching mode.
+You can then type either a search string, or use one of the additional key-bindings
+to change the behaviour of the search.  C<C-h> provides online help regarding
+the possible interactive options.
+
+=head3 EXTENDED USAGE:
+
+It is possible to pass arguments to the C</ido_switch_start> command, which
+correspond to some of the interactively settable parameters listed below.
+
+The following options are available:
+
+=over 4
+
+=item C<-channels>
+
+Search through only channels.
+
+=item C<-queries>
+
+Search through only queries.
+
+=item C<-all>
+
+search both queries and channels (Default).
+
+=item C<-active>
+
+Lmit search to only window items with activity.
+
+=item C<-exact>
+
+Enable exact-substring matching
+
+=item C<-flex>
+
+Enable flex-string matching
+
+=back
+
+I<If neither of C<-exact>, C<-flex> or C<-regex> are given, the default is the value of
+C</set ido_use_flex>>
+
+=head4 EXAMPLE
+
+=over 2
+
+=item C</bind ^G /ido_switch_start -channels>
+
+=item C</bind ^F /ido_switch_start -queries -active>
+
+=back
+
+B<NOTE:> When entering window switching mode, the contents of your input line will
+be saved and cleared, to avoid visual clutter whilst using the switching
+interface.  It will be restored once you exit the mode using either C<C-g>, C<Esc>,
+or C<RET>.
+
+=head3 INTERACTIVE COMMANDS
+
+The following key-bindings are available only once the mode has been
+activated:
+
+=over 4
+
+=item C<C-g>
+
+ Exit the mode without changing windows.
+
+=item C<Esc>
+
+Exit, as above.
+
+=item C<C-s>
+
+Rotate the list of window candidates forward by one item
+
+=item C<C-r>
+
+Rotate the list of window candidates backward by one item
+
+=item C<C-e>
+
+Toggle 'Active windows only' filter
+
+=item C<C-f>
+
+Switch between 'Flex' and 'Exact' matching.
+
+=item C<C-d>
+
+Select a network or server to filter candidates by
+
+=item C<C-u>
+
+Clear the current search string
+
+=item C<C-q>
+
+Cycle between showing only queries, channels, or all.
+
+=item C<C-SPC>
+
+Filter candidates by current search string, and then reset
+the search string
+
+=item C<RET>
+
+Select the current head of the candidate list (the green one)
+
+=item C<SPC>
+
+Select the current head of the list, without exiting the
+switching mode. The head is then moved one place to the right,
+allowing one to cycle through channels by repeatedly pressing space.
+
+=item C<TAB>
+
+B<[currently in development]> displays all possible completions
+at the bottom of the current window.
+
+=item I<All other keys> (C<a-z, A-Z>, etc)
+
+Add that character to the current search string.
+
+=back
+
+=head3 USAGE NOTES
+
+=over 4
+
+=item * 
+
+Using C-e (show actives), followed by repeatedly pressing space will cycle
+through all your currently active windows.
+
+=item *
+
+If you enter a search string fragment, and realise that more than one candidate
+is still presented, rather than delete the whole string and modify it, you
+can use C-SPC to 'lock' the current matching candidates, but allow you to
+search through those matches alone.
