Notational Velocity combines the search and title fields, so while you type the title of a new note, NV is searching for notes that contain those words, and filtering out notes that don’t.
To see the full list, simply delete whatever is typed in the search/title field, or press ESC.
Just start typing a new title in the top field and press Return. (Don’t worry, the old note won’t be renamed.) You can also restore your search terms by pressing Command-D, to avoid re-typing them.
Double-click its title in the list, or press Command-R.
Under Preferences > General, uncheck “Quit when closing window”.
From the View menu, select Sort By > Date Modified. You can add the Date Modified column by choosing Columns > Date Modified.
Go to Preferences > General > List Text Size to change how the list of notes appears.
Go to Preferences > Fonts & Colors > Body Font to change text in the body-editor.
NV selects the first word of your highlighted search terms. If the body area is not active, then Mac OS X will use the inactive selection color, which is light gray. To more easily see the first highlighted word, press Tab to make the body area active.
Notes are stored in your home directory under ~/Library/Application Support/Notational Data/. This folder can be moved using the Finder; see Moving/renaming the notes database. Note: On OS X 10.7 Lion and higher, the Library folder in your home folder is hidden by default. To open it:
Under Preferences > General > Bring-to-Front Hotkey:, click “Set”, and press your desired combination of keys.
To keep Notational Velocity running even after its window is closed, so that it can listen for your keystroke, uncheck “Quit when closing window” under Preferences > General.
Under View > Columns, uncheck all columns other than Title (i.e., hide the Date and Tag columns). NV hides the column names automatically when the Title column is the only one visible.
