A couple of prepared mouse gesture collections you can import into KHotKeys in KDE 3.2. Each of them are organized as group so it's easy to selectively disable them as groups without going through every single action for doing so.
|Opera style||List of Opera mouse gestures|
|Mozilla style||List of Mozilla mouse gestures|
|Search from everywhere||Opens Konqueror searching google for selected text. Mouse gesture: Left-Down-Right (square C)|
|PalmOS Graffiti edgy style||Graffiti Chart, since KHotKeys currently only detects edges and no round shapes these are a pain to use|
Some little documentation, multimedia shortcuts and an effort for a collection of mouse gestures and shortcuts for inclusion as defaults in KDE 3.2.1 can be found at Lubos Lunak's page.
