Entry of numerals, letters and characters

lowing:

Character set

Numerals 0 ... 9
Letters A ... Z
Punctuation marks . -
Operating principle
Characters can be entered as long as an input field is displayed.
The keys of the alphanumeric are assigned to the characters that are
printed on them. Example: With the
following characters: 7, P, Q, R, S.
The required character is selected by pressing the key several times
(similar to a cell phone). The numeral appears on the first pressing if
the key is assigned to several characters. One keypressing is sufficient
to enter a numeral.
The key for punctuation marks (<- .>) is assigned to a decimal point of
minus sign, depending on the context. If a number is in front of the
punctuation mark, a decimal point is automatically displayed, in all
other cases a minus (-).
A character is taken over in the input field if
the character is highlighted longer than one second,
the character is confirmed with
another alphanumeric key is pressed.
Operating example:
Entering an ID
The input field for an ID appears if you press the
measurement data. A dialog with input fields for the ID and comment

"Test" should be stored.
