I would like to specify a large tab size (say 16) for TSV files, but have normal tab size of 4 for other files/languages. I went View/UserDefinedDialog, made a new language, click SaveAs TSV. Specified file extension of tsv there, nothing else. Didn't see any tab options in the new lang dialog. Next I went to Setting/Preferences (tab: Languages/Tab Settings) expecting to see a new language of TSV in the list where I could set the larger tab size. But there is still no entry in that this for TSV. I can see TSV in the Language menu item, after the built in langs, and before the User Defined item.
Thanks
