Incremental search (Ctrl+J)
First of all if you miss "/" command of your favourite vi editor the Ctrl+J is what you need. Once you type pharse you looking for (look at status bar - red color surprisingly means "sorry no match"). But if you are lucky "Up/Down" key buttons allow you navigate back and forth among all found matches (b/n for vi masters ;>).
Open Type (Ctrl+Shift+T)
Immortal Ctrl+Shift+T works as well allows you open any Type available in workspace.
Quick Outline (Ctrl+O)
Ctrl+O invoke nice yellow frame with outline view. Local search ability and "Up/Down" keys allow you handy navigation.
