Series 3100/3500 Product Reference Guide

Modifier Keys

The <Shift>, <Alpha>, <Func>, and <Ctrl> keys are modifier keys. When pressed
individually or in certain combinations, these keys change the keyboard state and
possibly the character produced by the character key subsequently pressed.
For example:
• Pressing <Alpha> causes the numeric keys to produce letters. (Lower case letters
are not available on the 35-key terminal, but they are available on the 46-key
terminal.)
• Pressing <Func> followed by <Ctrl> produces Alt characters, with the same
effect as pressing the Alt key on a PC.
• Pressing <Func> and a scanner trigger enables that trigger for scanning. (Refer
to the section Scanning for more information.)
• The opposite trigger is another Alpha key (Alpha Shift), producing capital letters.
It is active only when held down.
• The <Alpha> key on the keyboard affects all succeeding character keys until
<Alpha> is pressed again. The other modifier keys affect only the next character
key.
Refer to Appendix B for the characters and operations produced by pressing a
sequence of modifier keys on the standard terminal keyboards. These key assignments
can be changed by an application. Refer to your application documentation for any
special key assignments.
Cancelling a Modifier Key
To cancel the effect of a modifier key, press it again.
Keyboard State
The cursor's shape indicates the current keyboard state, unless changed by the
application. The standard cursor shapes are shown in Table 6-4, Cursor Indicators.

Key Descriptions

Most of the keys are self-explanatory. Letter keys produce letters, number keys produce
numbers. Keys that perform special functions are described in Table 4-1, Special Keys.
