  • IPv4 and IPv6 addresses are clickable now, and clicking IPv4/IPv6 addresses will display a web browser and shows the IP information. Moreover, hovering over IPv4 addresses will show you the country name where the IPv4 address was registered (In order to use this feature, you will need to download an additional file. See Remarks below.) The behaviors are customizable by editing the macro file.
  • Hexadecimal colors and RGB colors can be clicked to show the Color Picker and allows you to select and change the color value.
  • The behaviors of Active Strings (including URLs, email addresses, IPv4 and IPv6 addresses, strings enclosed by quotation marks, HTML Character Reference, Universal Character Names/Percent-encoding, Hexadecimal colors, and RGB colors) can be customized to run macros, external tools, or EmEditor commands, in addition to previous behaviors.
  • The Link page of configuration properties allows you to specify which strings act as Active String. The new Active String page of the Customize dialog box allows you to specify a behavior for each event such as Left Click, Left Double-click, Middle Click, and Right Click of each Active String.

In order to inspect the name of the country where the IP address is registered, download the GeoLite2 Country database, unzip and place the extracted CSV file in:

  • If an EmEditor installer was used to install EmEditor (using the Registry):
    %PROGRAMDATA%\Emurasoft\EmEditor\data, i.e. C:\ProgramData\Emurasoft\EmEditor\data
  • If a portable version of EmEditor is used (using INI files):
    data” subfolder of the EmEditor installed folder, i.e. X:\…\EmEditor\data

It is recommended to download and update the above file periodically since the database is updated frequently.


The new IPTip.jsee macro uses the GeoLite downlodable CSV data created by MaxMind.
