Getting Around in Salesforce1
When users log in to Salesforce1, the first thing they see is a landing page. The first item in the Salesforce1 navigation menu becomes a users’ landing page by default. If your organization has Chatter enabled, and you haven’t customized the Salesforce1 navigation menu to change the first item in the menu to something else, the user’s Feed will be their landing page.
The Feed
The Chatter feed shows users their updates, updates to records and people they follow, and updates in groups they follow. Tapping a feed item displays all of the item’s details. Pulling down on the feed reveals the search bar (1), sort and filter options (2), the feeds drop-down menu (3), and feed items (4).

From the feed, record pages, and from elsewhere in Salesforce1, users access actions from the action bar.
The Action Bar and Menu
Depending on which feed or record page users are viewing, they see
different actions in the action bar and action menu. From the feed, for example, they see a
set of global actions. From a record page, however, they see a mix of productivity actions,
standard and custom buttons, standard Chatter actions such as Post and File, and global and
object-specific actions that are assigned to the layout for that record type. Users can tap
from the action bar to open the action menu, which
contains the full set of actions that are available for the object.

The Record View
The record view is made up of the record feed, detail, and related information pages, which your users can swipe left and right to see. If your organization doesn’t have Chatter enabled, the record view only includes the detail and related information pages.

At the top of each record page is the record highlights area. The icon for standard objects is predefined in Salesforce, and you can select the icon for a custom object using the custom object’s tab style.
You can customize the fields displayed in the record highlights by using compact layouts.
