Easily add special characters to a post, e.g. the Ω - Windows users only :(

[Harald Kapp]

The number of special symbols available from the drop down menu when writing a post is limited. A very common missing symbol is the Ω.
Autohotkey can be used to circumvent this. I use the following little autohotkey script:

#Singleinstance
::ohm::Ω
::kohm::kΩ
::mOhm::mΩ

This script is loaded by Windows upon the text ohm by the symbol Ω.
To type Ohm without substitution, simply press CTRL-Z when autohotkey has replaces the text by the symbol. You then get the text without replacement.

The script can easily be amended to perform other substitutions as required, see the documentation and the forum.
Note that there are Versions V1 and V2 of autohotkey. I strongly recommend to go with V2.

The Ω symbol can also be directly generated by Alt234 in Windows.
Alt230 generates the µ symbol.

Yeah, any character can be generated by an ALT+nnn or ALT+nnnn escape sequence.
For me the autohotkey variant is easier to use, although there is at least one case where I resort to the ALT method for a not so often used special character.

I recently got ChatGPT to list all the maths and Greek characters , saved the list as a file using Wordpad, and now can copy and paste any wanted character from that file.
