Label; Checkbox; Radio Button; Button/Icon - ELCOM POS-3000 User Manual

ECR description
Following text explains several terms that appear in computer terminology. They are needed
for good orientation in the texts of following chapters.

Label

Label is a fixed static text which function is to describe other element or its function/meaning.
Labels may also serve themselves as a source of information.

Checkbox

The checkbox is a square shaped element that can be either checked (on) or not. The check-
box is toggled by pressing its square shape or by selecting it using Tab keys and toggle it using
Space.

Radio button

The radio button is an array of circular elements within a group that offer different choices
to the user. Selecting one button from within the array automatically cancels previous selec-
tion (just like old-style radios do). Pick one button from the group using Tab keys and press
Space.

Button/Icon

The button is an element on the display that, if activated, will perform its assigned function.
You can press the button directly on the touch sensitive display or you can pick the desired
button using the Tab keys and pressing Space afterwards. The icon is in fact a button but con-
tains iconic representation of the intended function. The icon is employed in the same way
the button is.

Text row

Text row represents the place where data can be entered and not only text data. Typical exam-
ple is the entering of cashier's password into the text row.

Pull-down menu

The pull-down menu serves as to pick one option from several options. The visual difference
between the pull-down menu and the text row is the small square carrying an arrow on its right
side. When pressing the square, the menu unfolds and the visible unfolded options are selected
by pressing on. While keyboard serviced, the menu turns blue if selected using tab keys. Use
up and down arrow keys to browse through its options.
