Extra Keys Pro is an extended edition based on the basic Extra Keys tool but with the important additional feature of being able to output each character in several different encoded formats. Like the standard edition it is now free to use.

In this case "Pro" stands for "Programmer". If you need to edit HTML web pages or program source code files then this is the edition for you. It also has additional key-sets and configuration options which may be of interest to other users who want more features than the standard edition.

There are many situations when it is not advisable to use some characters in source code files. They should instead be entered as an HTML entity, decimal or hexadecimal code. Extra Keys Pro gives an easy and quick method to do this.

As well as sending plain characters to other applications and the Windows clipboard (exactly the same as the standard edition) the Pro edition is able to output in these formats:

  • HTML entity name
  • HTML entity code as decimal
  • HTML entity code as hexadecimal
  • Unicode code point
  • "\u" escaped 4 digit hexadecimal
  • "\U" escaped 8 digit hexadecimal
  • percent encoded UTF8
  • decimal character code
  • hexadecimal character code, with 3 different prefixes (0x, $ or &H)
