With simple :File commands, you can make Qedit tolerant of your most common typing errors in filenames. For example, I frequently mistype the name of my daily diary file as "dairy" instead of "diary". Qedit always responds with "NONEXISTENT PERMANENT FILE". All I need is one simple file command, which I have put into my Qeditmgr configuration file:
:file dairy=diaryNow, no matter whether I type dairy or diary in my Open command, I get the proper file.
