The results are shown pretty fast, it usually took less than a second for them to be displayed on the page. The Firefox add-on makes use of three different keyboard and mouse shortcuts. Pressing Shift and clicking the right-mouse button will look up the selected word in Wiktionary, while Ctrl and the right-mouse button will look it up in Wikipedia. The last shortcut can be used to open the quick search dialog. The shortcuts can be customized which might be necessary depending on other add-ons installed on the computer.

QuickWiki is an experimental Firefox add-on. This means that it can only be downloaded and installed after logging into the Mozilla website. It has to be noted that the add-on is currently only working with the English language portals of both Wikipedia and Wiktionary.
