Galaxy S4 “hidden” features

In a new blog post, Samsung describes ten “hidden” or “semi-secret” features of the Galaxy S4, which some of you may not be aware of.
Coincidentally or not, the Samsung post went live on the same day Verizon and Motorola unveiled new Droid smartphones, and a day ahead of the upcoming Nexus 7 announcement.
Here are these semi-secret Galaxy S4, as tipped by the company:
 


1) Swiping down with two fingers offers access to the full Quick Settings panel. (How: swipe down from the status bar with two fingers. Touch and hold to access settings. Long-tap an icon to drag it into a different place.)

3) The keyboard can be pop-up-ed on top of other apps for multi-tasking-like features. (How: With the keyboard active, tap the settings icon on the left of the space bar and then select the pop-up keyboard icon.)

5) A Wi-Fi timer app should help users save cellular data, as the phone will try to connect to available Wi-Fi networks for a specific period of time. (How: Settings > Connections > Wi-Fi > Advanced > Wi-Fi Timer.)
