Everything in Slash for iOS happens from the bar along the bottom of the screen. What it does follows the extension you're in.
- Tap the bar to type — a new task in Tasks, a note in Notes, a reminder in Reminders, an address in Browser.
- Tap the search button beside it to filter the list you're looking at.
- Tap the switcher button to pick another extension, or swipe along the bar to move to the next one.
Home shows every extension as a grid — Tasks, Notes, Reminders, Browser, Calendar, Bookmarks, Drop, Deck, Trackpad and Airmouse — and the switcher lists them all too. Swiping the bar can be turned off in Settings.
