//
// Ubiquity for Opera? A nightly experiment...
// http://github.com/cosimo/ubiquity-opera/
// -------------------------------------------
//
// An attempt to rewrite Firefox's Ubiquity extension
// for Opera using UserJS.
//
// Original Ubiquity Project: http://labs.mozilla.org/ubiquity/
//
// To use this in Opera, you need to:
//
// * Enable UserJS. Point your browser to opera:config#Javascript and:
//
//  - tick "User Javascript" checkbox
//  - type the folder you want to run the scripts from
//    in the "User Javascript File" textfield
//
//  If you want, you can also allow UserJS execution in
//  HTTPS pages.
//
// * Remove the default shortcut key bound to CTRL + SPACE,
//   since the original Ubiquity is activated and deactivated
//   with CTRL + SPACE.
//
// Have fun!
