Since “Ctrl+I” is shortcut for italicizing text in some software applications,
the result of above output sequence can be a regular A plus an italic F.
Please note that Ctrl Mode is only supported by English (USA) keyboard
layout.
(2) Alt Mode:
When virtual keyboard and alt mode are enabled at the same time, the
control code output will be ALT + ASCII Decimal Value. For <HT>, the
output sequence of virtual keyboard is:
Enter “Alt + 0 + 9” – Virtual keyboard will press and hold Alt key, press “0”
and “9” on numeric keypad respectively, and release Alt key.
When in standard keyboard, control code (0x00 ~ 0x1F) will be sent
according to its function key definition, as seen in below table:
