% Keyboard: The Keyboard and Touchpad

TODO: \<We should have a picture of 1.5 rather than 1.0\>
The keyboard and touchpad—which are dust and water resistant—have
special keys for additional functionality. Keyboards are designed for
each country, so your keyboard may not look exactly like the one in this
figure. Keys outlined in yellow are reserved for future features (such
as the "grab" keys and the "slider bar").
1. Escape key -- The escape key is labeled with an × symbol on a black
circle. The escape key is most commonly used in combination with the
control key to quit activities (ctrl + esc).
2. Tab key -- The tab key is labeled with arrows pointing right and
left. The tab key—in addition to its standard use—is used in
combination with the control, shift and alt keys to cycle through
open Activities. For example, alt + tab cycles forward through
running Activities.
3. Control key -- The control key is used in combination with other
keys to issue commands. For example, ctrl + c is used to copy to the
clipboard; ctrl + v is used to paste from the clipboard.
4. Shift key -- The shift key is used in combination with other keys as
a modifier, most commonly to shift between lowercase and uppercase
in Latin-based alphabets.
5. Fn key -- The function key is used in combination with other keys as
a modifier. For example, fn + erase is delete; fn + up arrow is page
up.
6. Alt key -- The alt key is used in combination with other keys to
issue commands. For example, alt + enter toggles full-screen mode;
alt + spacebar toggles the tray visibility. This example works in
the Browse Activity but not in the Record Activity.
7. Spacebar -- The spacebar key types a space. In the future, when used
in conjunction with the function key (fn), it will eventually view
the source code for the currently running Activity.
8. Alt Gr key -- The alt graphics key is used in combination with other
keys as a modifier, most commonly to select an alternative letter or
generate an accented character. The details of this functionality
vary from keyboard layout to keyboard layout: for example, on the US
keyboard, alt gr + j generates a € (euro sign); typing the character
"a" followed by alt gr + 4 generates á.
9. Arrow keys -- The arrow keys are used for navigation; combined with
the function key (fn), they are used for page up, page down, home,
and end.
10. Language key -- The language key is found on keyboard layouts that
combine Latin and non-Latin scripts. It toggles between scripts, so,
for example, one can switch between typing in English and Hindi with
a single keystroke. (On Latin-only keyboards, the language key has
been replaced by a × and ÷ key.)
11. Enter key -- The enter key—in addition to its standard use—is used
in combination with modifier keys. For example, alt + enter toggles
full-screen mode.
12. Erase key -- The erase key deletes the character behind the cursor
(backspace). fn + erase deletes the key in front of (or on) the
cursor.
13. Frame key -- The Frame key toggles the presence of the Frame on the
screen. The Frame is the black border around the screen that holds
the Activity taskbar, clipboard, wireless connections, battery
level, and so on.
14. Volume controls -- The volume keys lower and raise the audio level.
15. Brightness controls -- The brightness keys lower and raise the
brightness of the screen backlight. To turn the backlight off
completely may take 7-8 button presses.
16. View keys -- The four view keys, from left to right, take you to the
Neighborhood view, the Group view, the Home view, and the Activity
view.
17. Search key -- The search key takes you directly to the Journal and
places the text cursor in the search box.
