Now New Laptops/Notebooks/Tabs coming in market,
does not have Numerical Keypad on Keyboard
or any NumLock Key
which can provide a Virtual Numerical keypad.
Sot Input of any Unicode Character with
Alt+Decimal Code of Unicode Character from Numerical Keypad
is not possible.
Input with Registry
Setting UnderHKEY_Current_User/Control Panel/Input Method
, set EnableHexNumpad to "1"
which provides Alt and Num Keypad's + sign and Unicode Numbers in Hex
also not possible.
It is also not practical to install many keyboard layouts.
Windows Alt+x feature only works in Wordpad and MS-Word, not in other applications.
So, it became a bare necessity to develop some Universal Input Method
to type any unicode character with
Alt+Hex Unicode or
Control+Hex Unicode or
Alt+CapsLock+Hex Unicode or
Windows key + Hex Unicode or
Any other key + Hex Unicode Number,
like Option/command+ Hex Unicode
works in Macs.
With regards.
