Rearrange file type dropdown

When I start a new file, the first thing I see is a dropdown list with file types from which I have to choose one.

Most of the time, I use 3 file types: Text, Pascal and autohotkey.
Text is the first entry in the list, Pascal somewhere in the middle and autohotkey at the very end of the list, so I often have to scroll the list.

Can I rearrange the order of the files, so that my dropdown list starts with the three types I need nearly all of the time?

Hello

You can't "rearrange" order of highlighters, but you are able to switch off unused highlighters in the highlighter settings - uncheck checkbox before highlighter name.
PSpad won't offer highlighters in the New file list or open dialog filters. But it will still detect highlighter and use them when you open any file.
