Is there a search applet like OS X's and is there a dictionary applet like in Xubuntu and Kubuntu? If so, how do I get them? By applets, I mean the ones on the panel
Artha is a handy English thesaurus having distinct features like look up on a global hot key press, passive notifications of a selected text's definitions, suggestions for misspelled words, etc. Once launched, it sits on the system tray monitoring for a pre-set hot key combination. When some text is selected on any window and the hotkey is pressed, it pops-up with the word looked-up. Should the user prefer passive notifications over the app. popping-up, this can be done by enabling the notifications option
Artha is available in the Ubuntu Software Centre for installation and come with a Panel indicator.
