UltraEdit has been around for over 20 years and is arguably the best text file editor in the business. So, here are some useful articles when working with UltraEdit:
I find that adding Word Files from Download UltraEdit wordfiles for syntax highlighting can be very handy. Personally I use "PowerShell" and "INI Files", I would use something for DOS Batch or Command files but last time I looked none of the options worked well enough, sadly. I have also used the YAML Word File, however it does not add much and I needed to edit it first to add the ".yml" extension.
When installing UltraEdit on CentOS I recommend you use the Fedora Install package as this works just fine. I downloaded the RPM file and then double-clicked on it, which opened it with "Software Install" which took care of the process. Once install it is available on the Applications menu under "Programming".
