The 58-Key Keyboard
The <BKSP/DEL> Key
The <BKSP> key (sometimes referred to as destructive backspace) moves the
cursor one character to the left, erasing the incorrectly entered key stroke.
The <DEL> key (<BLUE> <BKSP>) erases the character at the cursor position.
The <CTRL> And <ALT> Key
The <CTRL> and <ALT> keys modify the function of the next key pressed and are
application dependent.
The <TAB> Key
Typically, the <TAB> key moves the cursor to the next field to the right or
downward.
The <ESC> Key
Generally, this key is used as a keyboard shortcut to close the current menu,
dialogue box or activity and return to the previous one.
The <SPACE> Key
Pressing this key inserts a blank space between characters. In a Windows dialogue
box, pressing the <SPACE> key enables (√) or disables a checkbox.
The <SCAN> Key
Pressing the <SCAN> key – the yellow key with the star-burst scan symbol on it –
activates the scanner beam while pressed. For units that do not have internal
scanners, this key is inoperable.
3.4.3 The 58-Key Keyboard
In addition to alphanumeric keys that are directly accessible on the keyboard (no key
combination is required) and the keys described in this chapter, the 58-key keyboard
also provides function keys and macro keys.
Function keys <F1> through <F24> can be used with the CE operating system or
another application. The additional function keys – <F25> through <F30> along
with the macros are not used as part of the Windows CE operating system.
All function keys and macro keys can be custom defined for each application. The
Tekterm application utilizes these keys. Refer to “Additional Keyboard Functions”
on page 147 for details about Tekterm keys.
