Right-click a word in a document in Notepad view (or CTRL click for those of you without a multi-button mouse). You will see a >>word<< option. Click that, and you will see a the flyout populated with all other documents that have that keyword. Really handy in case you get sick and tired of opening a document to get at it’s keywords.
Either V1.9 or V1.9.x will probably provide the possibility to option-click on a word to simplify that job.
