It's a little odd that we're still using Notepad after all these years, but the truth is that there are some things that Notepad still does better than any other software when it comes to simple text files. KeyNote is there, however, if you ever want a Notepad program with more features, more versatility and more power.
The KNT - KeyNote Note File, is how KeyNote stores data. Inspired by Windows RichEdit, KeyNote supports a variety of advanced formatting options, along with various styles, macros and plugins.
If you're looking for a way to do simple text documents but you don't want to sacrifice things like formatting and rich text options, then KeyNote might be exactly what you're looking for. It's not as complex or as cumbersome as a typical word processor program might be, but it packs a little more in terms of options and versatility than simple Notepad. You get templates, macros, styles, formatting and plugins without some of the more extraneous features of something lik Microsoft Word.
In short, KeyNote is just the thing if you need your text program to be simple, but not too simple. KNT files are versatile and user friendly.
