I learned two tricks in the past two days on my computer, both embarrassingly foundational.
1. In Word: You can move text from one document to another by drag-and-dropping into the minimized window on the task bar. (Instead of cut-and-paste.)
2. In Windows: You can find a program quickly in "All Programs" by typing the name of the program. (Why aren't they alphabetized? Or is that another setting I haven't found?)
