Using the Modifier Keys
All three versions of the Dolphin 7400/7450 keyboard feature the standard PC keyboard modifier keys, Alt, Ctl and Shift. For
single-handed operation, the Shift key only modifies the next key pressed; it must be pressed and released before each key you
wish to modify. Functions of the Alt and Ctl keys are dependent on the software application in use.
There are two additional modifier keys located on the bottom row of the keyboard. Use these keys in combination with other keys
to type the corresponding color-coded characters and functions. The Red and Blue keys only modify the next key pressed; these
keys must be pressed and released before each key you wish to modify to the Blue or Red case. See the chart in Appendix A
for key combinations for keyboard functions and special characters that use these keys.
Other Special Keys
ON/SCAN Key
The ON/SCAN key wakes the terminal from sleep mode. Its position also allows convenient one-handed image-taking and/or bar
code scanning. On the 7450 terminal, the ON/SCAN key operates as an On or system wakeup control -- scanning is activated
with the handle trigger.
Shift (SFT)
The Shift key toggles the keyboard from upper case alphabet mode to lower case alphabet mode and back. Caps Lock may also
be toggled by pressing the red modifier key followed by the Shift key or by double-tapping the Shift key. When Caps Lock is
toggled on, the Shift key makes characters lower case; when it is toggled off, the Shift key makes keys upper case.
Enter (ENT)
The Enter key confirms data entry.
Escape (ESC)
The Escape key performs a cancel action.
Tab
The Tab key moves the cursor to the next tab stop or the next control on a form.
Light
The Light key toggles the LCD and keyboard backlights on and off.
Number Lock (NUM)
This key is included only on the 43-key keyboard option which defaults to alphabetic mode. The Number Lock key toggles
between the alphabetic and numeric modes.
Alpha Lock (ALPHA)
This key is included only on the 35-key keyboard option which defaults to numeric mode. The Alpha key toggles between the
numeric and alphabetic modes.
Backspace (BKSP)
This key appears on both the 35 and 56-keyboard options. The Backspace key moves the cursor back one space for each time
the key is pressed. Backspace is a shifted function on the 43-key keyboard version. To delete a single character, press Red key
+ SP. To delete multiple characters, press Red key + SP and hold down the SP key.
Delete (DEL)
This key appears on both the 35 and 56-keyboard options. The Delete key deletes one character for each time the key is pressed.
