Quick-add links appear as a drop-down list under the New button in the nav bar. Use this menu to create new records of various types no matter where you are on the site. Just choose the New button to the left of the search field and then choose an item type to create it.
Use the various check boxes under the Header Bar heading on the User Preferences page to establish the set of shortcuts included in the quick-add menu, thus fine-tuning the menu so it’s always relevant for your daily work. Select the check box for each feature you would like to include; clear the check box for each feature that isn’t relevant for your role in the system.
The One Click Task feature is slightly different from the other items here. This feature is only available on certain pages of the site, and appears in the toolbar rather than in the quick-add menu. Use it, for example, to create a completed task to log an activity such as making a call or sending an email (see also Manage tasks).
