This lua script gives you the ability, to search for selected text or word from cursor in an search engine or on an search site of your choice.You can select the engine/site from a list, that you have defined in your user properties.
To get the right call for your search engine, open the engine and search for one word. You need the url without the searched word. Write to your properties an display name for this engine and, separated by a comma, the url. See my example in the script header.
For the list with search sites, you need display name and site address (without http://).
It will searched for the full selected text or, if none selection exists, for the word touched by the cursor. You can allow in the properties, that also will recognized words with dots (like objVar.Property).
The script uses the shell.dll. But if you don't have installed it, the browser will opened with an command line call. Thats why the command window will pop up for a short moment.
You'll find details for installation and key bindings inside the script. Look for free command numbers in SciTE. By default installation, the numbers must be greater than 35 (max. 49).

This script publicates two functions
- InetSearch.Engine()
You can search for the selected/touched text in SciTE and can select a search engine of your choice.
- InetSearch.Site()
You can search for the selected/touched text in SciTE with a defined search engine and can select a search site of your choice.
Copy this script in your Lua scripts folder.
Load this file in the Lua startup: dofile("Full\\Path\\InetSearch.lua")
Add
in "SciTEUser.properties" the following properties with search engines and search sites of your choice:
#~ Inet Search Settings
#~ List of engines. "display-name,search-url" (if not set: google.com will used)
#~ If only one entry exists, the selection box will not shown.
