jEdit with typoscript syntax highlighting
A short tip; If you’d like to have syntax highlight for your TypoScript code in jEdit on *.txt files (apart from *.ts), then you would first install the TypoScript plugin, and then set (for instance) “First line glob” field under Global options to
//TSFILE
and type the same on the first line in you ts file. The next time you open it, it will highlight your code. Simple and effective.
